Car can't high boost and cuts Rpm
 

Hii,
My. And can't seem to run at high boost which is 2.1 bar and .. It stops at 6k rpm .. As the entire engine switches off and pulls to 7k rpm and switches off..

Anything below 2 bar is ok when I pull .. I pull at 1.7 bar and no problems.

Anyone knows what's wrong . Is it the coil pack ?

who did you tune with?

It sounds like fuel cut. I'd need to see a log and rom, but it can be remedied. It may need to be tuned as it may be seeing higher loads.

I had a similar problem, boost cut at 4000 and anything over 20 lbs, it was a bad waste gate that wasn't holding pressure properly and it was over boosting but the ecu caught it and shut it off. That's why I too thought it was a fuel cut.

Are you running a stand alone ems?

At 2.1 bar we are talking approximately 30 PSI, right? What turbo are you running OP?
