    Dz do you intend to run more boost? The RBs can take it right?
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    This car is driven hard on the road coarse, on pump gas, no meth. Yes, RBs can definitely take more boost but you have to consider a couple more things...

    More boost would make more peak power on dyno but would be bad on the road course due to heat (heat soak) introduced from the blowers. Its a balance and when we make these maps the first thing we try to understand is the sort of driving and what the car is being used for. There will be dyno queens, perfect weather conditions, show off type runs that some people want. Others want to run their cars predictably and controllably at the road course, while yet others will hit the strip and want that 1 pass in 20-30mins to be strong on race gas or pump+e85 and meth. Every car is a bit different, every driver wants something else with their car and on top of that put on differences in octane, weather, elevation, mods efficiency...equation is not fixed and every car is maximized in different ways...Some cars will take more boost less timing, some less boost more timing, throttle maps change, fuel mappings change, wgdc calibration etc etc.

    Really great results looking foward to you running it. Quick question what is the typical rate for a pro-tune?

    94oct FTW. His website states $149 for a tune, which is pretty damn reasonable.

    How's the eTune work?? IIRC it's basically an emailing back and forth of a couple of logs & making tweaks as you go along??

    Yes, it is an iterative process. People are highly encouraged to hit a dyno in the end and confirm before/after results.

    Truu.... Only problem is having access to a dyno/somewhere you can get some quality pulls in. Dzenno, hows the cylinder head that you were blogging about? I see that VAC is offering something similiar & just wanted to know if you had any #s on gains (I saw that there were very nice flow gains, wasn't sure about HP/TQ numbers just yet). Also wanted to know if you guys were putting the new cylinder heads with aftermarket or OEM snails..... Thanks in advance

    With meth, on Andy's car with results shown above, with exact same crappy weather conditions (say it was the same day), without retuning i'd expect it to instantly pick up another 15whp...i'm always on the conservative side so who knows, might be more...with a retune for meth and if we were to go all out AND keep the crap conditions the same I'd say another 30whp (again, maybe more)...so same conditions, with pump+meth and a retune, about 440-445whp conservatively speaking on THIS dyno in THIS weather...change the dyno and go somewhere with a higher baseline (some of which i've seen posted on the forums) and you get your glory run if you're into that kind of stuff...i personally don't care, we're here to show good deltas and custom made tunes to what the driver of the car wants out of their ride

    I am waiting word from the shop awaiting on my exhaust valves to arrive. No dyno numbers yet obviously as the car's in pieces at Columbus Automotive (Ivo's shop)...i can't wait for it to be retested on the flow bench with the new valves (also new springs and retainers by the sounds of it, titanium) and see the final numbers before slapping it back on the car

    As soon as I have something to share I'll update the cylinder head thread on here with more info...this head on my car will be used with RBs at the moment as that is what I run on the car right now...i wanted to go through VAC to do the head initially but they still had some work to be done with it at the time, were also very busy with their head porting guy having suffered an injury and being unavailable full time...in the meantime found an amazing local shop and went with them instead...i'm sure VAC won't disappoint, great shop from everything I've read so far!

    I wasn't sure if the upgraded cylinder head was going on his car or a car that he was working on (since he does COBB ProTunes).... That's why I asked

    No worries. The head, given everything goes as planned, will also make it on another N54 (535XI 6AT with RB turbos) right after mine is done. Depending on results on the dyno there may be great gains on stock turbos too. PAW Motorsports has claimed +40hp on stock turbos at just 14psi of boost by just unbolting the head and 100hp with upgraded turbos. Those are not my numbers. I'm just going by what someone else has estimated with their own work on the N54 head.

    Well I did it and it is still up, to bad they banned you because people posted some good questions, and your best one to answer them, I hope they change your status so you can give them the info they need.

    I'd be happy to give my car up (for the greater cause of the community of course) and try the upgraded head with my stock turbos. However, we should get a core or two in the cycle to keep down time at a minimum.

    Hmmm...... This seems like a more realistic gains right now since the aftermarket Intake/Exhaust manifolds are still in the R&D stages. The upgraded cylinder head should put an OEM Snail'd FBO N54 w/o Meth (thinking COBB Stg 2+FMIC Aggressive/ProTuned) just over 400 WHP Click here to enlarge

    Those are some great results, I'm in love with what I see after 5500rpm haha. It looks like the recent issues have scared a lot of people away from meth, but that kind of power on pump would be quite fun!

    If my turbo/tranny upgrade works out I'd much rather have you tune it than myself so I will definitely get in touch with you!

    These are great numbers indeed. Maybe I'll have to send you a PM next week when the RBs are operational. I'm not looking for a dyno queen either, it's not unusual for me to drive at very high speed/load for 5+ hours, so I like your approach on this particular tune, and I'm very impressed with the results Click here to enlarge

    There's more in that car. How's the tranny shifting? I know that was my #1 issue.

    When I was working with Rob, it seemed they got that part squared away, it was just dialing in the PID that was causing issues.

    This car I didn't want to push to the bleeding edge as its road course driven AND its pump gas only, at least at the moment it is. If Andy decides to run race gas and/or meth mix or just 100% water we'll retune and see where that takes it in terms of tuning. RBs definitely have more boost left in them given this is peak 18psi (hard boost limiter set at the same level as stg2+ agg map, didn't touch it) no doubt there's more left for down the road if so desired.
