Good morning all,

Im tuning my first upgraded turbo car and im running into a small issue. Around 6000 RPM boost goes flat and the throttle progressively closes to keep it at 15.1 PSI.

As you can see, I've pulled a ton of wastegate base and airflow out thinking it was just an over boost. Problem is, if I lower wgdc base/airflow the problem just follows it. I could set wgdc to 0% and it would still do the same thing.

This leads me to believe I've hit some sort of limiter. Datalog below:

Last night I raised the bottom rows of load to torque 1 through 3 and i'll post another log from that in a few hours.

Car is 09 335i with MMP Stage 1 turbos, Stg 2 fuel pump, Hotside inlets, and FBO, 93 oct


Thanks for your help
