    I'm not sure why you are reacting so negatively to my comments on "custom tuning"... I'm not saying you offer a bad service. I imagine a lot of people are happy to pay $250 to have someone help track down problems and set their boost curve. My point was little of what is happening here is really custom tuning. I used to tune standalone DFI systems, speed density, with narrow band o2 sensors, and all sorts of weird injector sizes. That was custom tuning lol. For the N54 you open the software and enter 11.8:1 and press save and the AFR targets perfectly unless there is some issue that needs to be resolved. Everything is basically canned. On piggyback map switching it sounds like you just don't understand how it works. When changing your boost profile on the JB4 you also change your timing and AFR targets if you set it up that way within the flash, and the JB4 dynamically adjusts the fuel trims. The JB4 also does something even more important. It levels out the fuel trims from off meth to on meth. It can even do this using an aquamist turbine flow sensor if running an aquamist kit. :) I guess most importantly for this conversation the JB4 lets you safely tune & log boost levels above 21psi without having to resort to risky duty cycle only tuning. As I always say the JB4 is just another tuning tool that can be applied in many ways. Obviously the JB4 has little to do with this new record. Whoever made the turbos deserves the credit. The JB4 was just there to make it easy for him to get the engine doing what he wanted it to do.

    Vertigo replied to a thread RE: Backfires on the N54 in N54
    I have also heard that removing all CATs and going to a full flow unrestricted exhaust system reduces back pressure to nill which can cause the exhaust valve seals to relax and let oil in. There was a post on here not too long ago regarding the oil seals and RB turbos.

    Not trying to poke the bear or anything, but if it's such an easy thing why didn't Rob, you or the other few companies that did upgraded stock-frame turbos do it a long time ago? Does it make the turbos more prone to failure to run them at that level?

    I pretty much just told you, we wanted to push what we sell to our customers to its absolute limits and do it for more than 5 runs before we started building one off stock frames to get to the 600WHP mark. We accomplished that, and now we will be doing exactly that. This is great for the community I love progress, but your cockiness for building a set of hybrids with bigger compressor wheels, and better aero turbines is pretty funny.

    No meth heads, meth kits or meth pipes. BMW F10 M5 made 670.8whp (771.42hp) measured on a good dyno with tune only. This M5 was tuned with our new direct ECU flash. We can now program the exhaust blip and the traction system, so it's not too sensitive which relates to more traction. This is also available for all 2014 cars with the new encryption. Speed limiter is removed and the transmission is also programmed. http://www.6speedonline.com/forums/bmw-m/344269-ecu-tuning-group-bmw-f10-m5-made-670-8whp-771-42hp-ecu-tune-only.html Anyone knows of these guys ?

    Just an FYI since were comparing RB components and ours. We did a direct same tune comparison Dyno graph with a an RB style 12 blade turbine wheel even with a billet 15T compressor wheel, and then using our custom Garrett 9 blade turbines with a normal Cast 15T. The 9 blades spooled the same or better than the 12 blades, and even with the less efficient cast compressor wheel just pulled away from the 12 blades up top. Also the 12 blade wheels, and the 9 blade wheels, weigh nearly identical, our billet comp wheels are lighter. It is the aero of the 12 blades that hold them back, not the weight. We offer them in our turbos as an option now strictly because people were asking for them. Blue line 9 blades, green line 12blades. Same tune, same fuel, same dyno. For the car here making almost 600WHP, what has been done there is not magic. Just physics and airflow. I was going to change things around a long time ago, but I wanted to fully test the limits of what we sell customers which is the TD04L / 15T combo first. Now that I am on an all out hunt for max stock frame power, we are making changes to achieve that.

    Vertigo started a thread P/P N54 Head in N54
    I just got the call last week that my head was ready to be picked up. Very happy with the work! To save on cost I decided to take on polishing the combustion cambers which is coming along nicely. I'm not going all out and didn't see any need for over sized valves as this is a spare head. .003 was taken off the deck but I am pretty set on using the stock (not thick) head gasket as I don't want the quench area to be too tall and have too much of the steel gasket sealing ring exposed during combustion and retaining heat. Between DI, running E85, and losing a slight amount of CR to the polishing of the CC I think I am making the right choice as this will be a daily driver and don't want to lower my CR too much. Once I decide to add a single, my hope is that the E85 will allow for higher boost without knock.

    @dzenno@PTF - without paying ptf or anyone with custom cobb software.... could this car have requested 28psi and hit 28 psi with an end user tuning with end user software ? I am not sure of this answer, not trying to fight here just genuinely curious. (when saying 28psi it is just a general number, i am not sure what @Blue24 ran , i am just generally speaking, but his boost was over what you usually see people use with RBs... I wouldnt push RBs to this level personally... Tonys seem to be able to hit more boost though as they are lighter, better components.)

    who cares... this car for example has logs that are happy and is making power with jb4... Tonys car has logs that are happy and is making great power with cobb, if the thing stays in one piece and the owner is happy why argue or try to argue about it... Terrys post is accurate in dons case. Everyone is busy Terry and Donny = really busy. Don has asked Terry questions over time. Terry shared a few things but nothing that lead Don to where he was yesterday. Donny did that but getting hardware in order, fueling system in order, and set a boost curve , hit that boost curve with a happy engine and made power. In other cars i am sure without attention from a custom tune it would never get to this point. But hardware condition is #1 priority , no issues is #1 a priority... that is what Terry was saying I think... doesnt matter who tunes a car if it has physical issues its not going to be happy and my point is how can one determine that who is tuning it when they are not present to actually see the car, test the car for those issues. We all want to reach the same goal. No one is here to fuck anyone else over. Lets not argue/fight... 594.7whp was made on a dynojet with stock frame turbos... thats what matters in this thread

    TheChasL started a thread Cobb AP in N54
    As much as it pains me to say it, I'm moving on from my N54 to the VW MK7 Golf R. As such I haven't any use for my Cobb AP I purchased in June of 2013 for $986 in Plano, TX. Holler if you have any interest as I'm happy with 50% back :) I might also be open to being convinced that I'm a complete moron and I should stick with the N54 platform. It simply seems all of the great mods are for the 1 and 3 series here, and the 5's are getting left behind... The VW Golf R with the Stage 1 Revo will do 0-60 in 3.6 seconds which is pretty darn amazing for a 4 banger.

    After a little more digging, I found that the part #17 was incorrect, sadly. It is for something in the trunk. However, if anyone else comes across this thread, I did find the correct part (the missing #9 from my OP) for sale on this site: http://parts.bmwofsouthatlanta.com/showAssembly.aspx?ukey_assembly=248989&ukey_make=972&ukey_model=13423&searchString=alternator

    Where do you get the energy for comments like this lol That can't be further from the truth and you know it very well. I do applaud you at your never ending persistence around this topic though. Most cars with a certain set of modifications and octane eventually end up in a similar "ballpark" from the tuning and power points of view provided everyone wants the same "type" of tune. Your canned flash and people stacking whatever boost profile they can dream up is one way of doing things but it certainly isn't the RIGHT or most optimal way of tuning any setup. When they start switching maps with steering wheel controls and just changing boost profiles on top of a canned flash or a flash they cooked up and "thought" worked well, with the cylinder 1-6 correction logging you added quickly realize how sub-optimal and broken the approach really is. All these years I've tried to highlight how bad the motors were correcting across the cylinders 2-6 that weren't loggable on the JB and that people shouldn't put too much comfort into cylinder 1 timing logs on their own. Now that its available with the JB and people start to appreciate where I was coming from. Why did it have to take this long to realize it? Another one I can think of that was continually brushed off by you and those unwilling to look past Terry's posts, to research and test for themselves, is post shift timing drop/fix that you and JB users raved about and claimed superiority of the stack over a flash tune with. Today the fix is found to be simply a misunderstanding as it was based on logs on cylinder 1's timing only, surprise? To those that ran without stacking, not at all. I realize this wasn't the topic here but your post above is simply misleading to most people that haven't had a chance to get really intimate with tuning in their day to day but have time to spend reading these forums. A lot of those same people don't understand how ignition timing should be tuned, how important true flow based meth failsafes are, efficiency, dynamic compression and cylinder pressures that affect motors over time (e.g. fatigue) from over-advanced timing curves for a given boost profile that over time wear down the motor (hint hint new M3/M4 JB owners just stacking boost on top of stock timing curves). Once again and I've said this before and I'll say it again: 1) There is absolutely no need to stack on this platform to get all the power possible out of this car for any given fuel setup. 2) To get the absolute best driveability that matches factory setup and dial in custom torque management/throttle mappings, your only bet is a proper flash tune. 3) The best way of tuning ANY motor, including the N54, is via a tune that has full control over all engine parameters. I am not saying PTF or Cobb or any other particular flash tuner. Stacking a piggyback works. Just because it "works" it does not imply it is ideal. In fact its completely unnecessary and in many ways a suboptimal way of tuning any motor. 4) Stacking piggybacks on the N54 has initially been frowned upon but then quickly and unfortunately been overhyped for the sole reason of staying relevant in this business on the N54 by Terry/BMS. It is a fact, neg away :) While piggybacks certainly have their place in the tuning world, once proper tuning with full control over all engine parameters is available (i.e. flash tuning, standalone) the right way of doing things can't be with the piggyback from that point on. For instance, the new M3/M4 owners don't have much choice outside the JB at the moment. Once flash tuning becomes available only those that don't really understand/care what tuning and complete control over all engine parameters is all about will continue to run a piggyback, or eventually stack. Those same users usually appreciate gimmicks such as in-dash gauges over a proper engine management system/tune. Cheers

    It's all about future performance relative to current cost. What he was putting on tape didn't match the $10.5mm cap hit he carries this year, and the $11mm cap hit he carries next year. My biggest concern is more on the locker room side. Hardly a mutiny brewing, but the players are pretty pissed as I understand it. Mankins very, very well liked and respected among everyone in the building. Same deal happened with the Seymour trade in 2009, that locker room was a mess. This group has far fewer rotten apples than the 09 team so i'm not as worried, but still. Worth considering when the going gets tough.

    So will the details of what upgrades were done to the turbos to squeeze this type of power? Also will you be releasing or selling the backend used to milk that type of power? This is exciting stuff, I am real close to pulling the trigger on a single kit but this stock frame business has me interested for sure..
