Stuttering problem when at 100% throttle
Well here is the deal I have a Megan Racing Manifold, Downpipe, Test Pipe, Stock Cat Back and a Vishnu XEDE. Well in 3rd or 4th gear whenever and only when I get on the throttle 100% in the 4000 and up range it'll randomly stutter. It feels like I hit a wall and then it pulls again and it stutters again sometimes and eventually the CEL gets thrown.

whatever the 330 + map is pushing, My boost guage shows it building to 21 and in some cases 23 in 5th gear. Also my bumper by my exhaust is black so maybe even with the Vishnu maps I am running too rich?

Did you by any chance take your car to the dealer and have it serviced? They might have reflashed it with their own software because of some code and that may have messed it up. I had the exact symptoms right after my car got reflashed for a code by my dealer, but I never put two and two together. I just thought that it was something that happened once in a while. Then finally when I took my car to Vishnu to get Stage 2'd, they told me the car was running funny and one of the first things they asked me was if the dealer had reflashed it.
