    [QUOTE=Tony@VargasTurboTech;629418] Pulsations...

    Pulsations are a pain in the ass to deal with. One of the real issues is that the equipment isn't high enough resolution to capture the true peaks and valleys going on.

    System piping is a huge...

    Steve has a thread on N54 tech that he talks about it -"Fuel-It TB/port injection". I don't want to overstep my boundaries; I'm part of the Fuel-it! team but really more on the tech side than the...

    The 550i clutch is holding up as expected -no issues at all. I'm even used to the chatter from the SMFW now.

    The Fuel-it! stage 2 Low Pressure Fuel Pump is doing just fine -it's a robust unit and...

    Yes! Sort of. Got the intakes on, got a basemap, it ripped but I am out of fuel up top pretty significantly. Need to address that next. Bren toned down the wgdc, which is why I think spool slowed...

    I went from a Legacy GT with Wisecos and a 18g to the 335. It was a fun car.

    No clue. Okay, that's a lie. I DO have a clue.

    Ham-fisting the GD'd connectors on & off a bunch of times. I probably inadvertantly pulled/tweaked/whatever. Probably just a pin that was not...

    I had those codes when my N20 harness failed. A replacement fixed it.

    Yeah... the power level not falling like a cliff makes the car feel totally different. I expected it to feel different but not THAT different. It's a beautiful thing.

    I have the quickest spooling of the VTT2+ versions... 19t/unclipped. I have VTT inlets as well.

    Lag is partly a function of the tune for sure, but I was pretty surprised when I first ripped...

    Brentuning does etunes, he is an authorized Cobb Pro-Tuner. I've had nothing but good luck from him for many years on several platforms. He's a friend of mine too, so I am biased. His tunes are...

    Dude, go away.

    Stop spewing your bull$#@! about Virtual Dyno and other people's intakes and stock turbos in a thread that has "upgraded" right in the title. Please go do your own thing with your...

    Oh, right.

    1: Backpressure isn't the term normally used on an intake system but it's not wrong. It's fine. I wouldn't argue it and I wouldn't like too many conversations with someone who does....

    VD is a useful tool that's as good as the data you put in it. I'm not going to argue VD versus a real dyno for ultimate power measuring but it's pretty damn good for showing deltas. On the other...

    Not really a BS attitude. His go/no go gauge is that you can easily suck in foreign objects and trash your turbo, so who cares if it offers a little more power, it's a no go. That's basics. You...

    Pretty lucky here in AZ. Rarely changes much at all. I don't even test it any more except somewhat randomly.

    Good question. There are a couple things that it *might* be.

    I suspect the biggest thing was that I asked Bren to tone down the WGDC as a tweak to my last map for these intakes. I swapped to...

    lol

    Bren is not an amateur. Of course I have overboost protection. All safety mechanisms are in place.

    He has scaled the voltage from the map sensor. The principle is not complicated but it...

    Holy $#@!, they made that much power on oem turbos?

    Yes, Cobb only. I'm using the 3.5 bar N20 MAP sensor and Bren has scaled the voltage to allow higher than the ecu limit. No scaling required for at least my version of the ecu unless it's over 22.5...
  21. No guys, this is with upgraded stock frame...

    No guys, this is with upgraded stock frame turbos. These are the VTT 2+'s, 19t, unclipped turbines. This is a fairly tame map Bren drummed up for my daily driver with 108k+ on it. Running approx 25...

    That's my car!

    Yeah, the VTT inlets removed the pre-turbo restriction of the stock inlets. When you starve a compressor for air, it behaves like the turbo is at altitude. The compressor has to...

    I have occasionally seen temporary limp modes when flashing a new tune. I clear them and they never come back. That said, you should be logging and if you get a limp mode, scan the car before...

    Few months... relatively new. I haven't tested it yet but it seems to run okay in my car. Next time I'm through there I'll try to get a sample to test E%.
