I don't think its a fueling issue. I was autotuned to 15.2 on v4 and never got a limp. Shockin was at 13.5 (below this supposed threshold).

You were runing 13.5 when it happend or 13.5 max PSI?
I thought it was a universal thing across all transmitions but I guess not...in my DCT I can't go past 14.4 or it does it. Now, I can run more then that but only for single gear pulls not if I go through 2-5 or whatever. |

it atlso seems to my that cars with diferent trans hold boost different. there was some talk about how the MT whould boost creep past the target PSI but my DCT car has never done this, my boost peaks at whatever PSI i set it to and it taper down to 11~12 PSI by 6500 RPM so the trans in the car might have something to do with it.....

Well I stall at the line, 2k rpms. 1st gear comes, but I can tell power isn't really there, boost is, but not power. 2nd gear comes, then right about 6800rpms the car goes into limp mode. No power what so ever.

So the most the N55 can run as for boost levels is 12 psi? I read somewhere Shiv state because of turbo efficiency for the twin scrolls and pushing anything more would need a single turbo upgrade? If thats the case, N54 FTW!

Well being that stock id run 13.9s at 100 this isn't too bad. Running about the same boost right now as the jb3, and with the jb3 I hit a 13.17@104. So I saved off about .15 s and gained 3mph. Granted the car wasn't fully adaptive. I kept upping the boost after every run.
