Default Car cutting out at WOT - No codes present
Any help from the experts would be greatly appreciated.

Here is the stats

Stage III 1.8T at WOT cuts in and out causing the car to severly jerk. No engine codes. Car runs fine when your not in WOT. Also, runs strong at WOT when manually put into limp mode by disconnecting the MAF (exception of boost being 7psi).

Any thoughts. Thanks

Diverter valve, vac leak, or N75 are good places to start.

Pressure test the system. There should be a good writeup in our awesome FAQ up top.

Default can still get misfires at WOT.
had that issue. Car was running rich and a bad coilpack

rich = coolant temp sensor
