So as some may know I have been battling this issue for quite a while now.
The car is running a stage 1 tune for around 2 years. And before someone goes in the direction that something is wrong with the tune. I already tried 5 different ones. With the same results.
Short story. Have a new pcv, dv, maf, turbo (oem) and checked for boost leaks. Only thing I haven't changed is the MAP which I've ordered since it's dirty cheap.
I also have some like cuts at between 3-4k rpm almost like missfires.
MAF / Load
Boost / Timing
Boost / Fueling
