I didnt think so either but i figured it was worth a shot. I wont be able to test for a boost leak for a while. I did change my boost duty start % a little while back on my AVCR. I dont know if that would do it either. I will check out that theory tomorrow. I am really lost on this one. It will go to 0lbs or slight vacuum and stay there.

is the 2-step working? I mean it's holding the RPM right, not just revving to the moon...

That is correct. If i just leave it in neutral, and rev it, it will go to redline and build a little boost, but with the clutch in, in first, at a stop, it bounces at 5700 and builds nothing. Very frustrating.

Just took a couple logs and noticed that my 2 step log only shows my throttle % at 36% while its floored yet my 3rd gear pull shows 100%. Any ideas?

woah, sounds like you found the problem...that's definitely odd. I've never heard of that. Bad TPS sensor or adjustment?

I know it doesn't make sense but maybe you can borrow on from another car just to rule that out so you can move on.

also try loading a bone stock ROM just to make sure there's not something in your tune causing a problem.

I dont know what the hell is going on. I re-flashed it with the same map and now it seems to work fine. I will monitor it and keep everyone in the loop.

sounds like the ROM didn't flash properly last time, did it get interrupted last time? lost power or got disconnected?

Not that I know of. I am just as confused as you. I never had any wierd errors when flashing. On a side note while i have a tuning pro's attention.....i have looked up injector scaling and am somewhat lost. I am installing 850cc's with a new turbo in a few weeks, can you point me in the right direction as what to adjust for the new injectors??

well, thats information I sell

however there's a thread on here where some people are sharing that info...some of it's terrible though likely because they were dialing in the injectors with boost/vacuum leaks or just plain don't know what they are doing
