Hey guys how you doing.. To start off here is whats done to my gti
-frankenturbo f21
-415 cc genesis injectors
- stage2+ unitronic tune
- stage 2 coolingmist meth injection
-fmic, turbo back exhaust, to a dump pipe

Recently as i was driving when i hit full throttle the car hesitates at 4k rpm then opens up at 5k
But every time i go past 6k ([email protected] 7250) check engine light flashes and i lose power, now i changed the spark plugs, and coil packs are good as new, but still have the same problem, any suggestion? Thanks in advance

Well you're not hitting the fuel cut unless your still running the stock 3 bar fuel pressure regulator. When did you last replace the fuel pump.

And on a side note I hope you're not running the stock rods. If you get a boost spike like I did on stock rods say goodbye to the rods

I don't know if this is the problem but maybe your mass airflow sensor is bad. When i bought my car i couldn't go over 4,000 rpms and then it would bog out and have very bad respond. i changed it and it worked great. Just an idea!
