LS2 / with a ProCharger Hello everyone. Had a quick question, have a 05 GTO with a procharger on it. I'm having a problem with the car hitting the limiter at 5,000 rpm's. The stock limiter is still set to the factory 6,600. I'm using HPTuners for the editing. The only are that I have edited so far is the injector table, ignition table, and the ETC vs TPS table. Just wondering if anyone else has expierenced this problem. Thanks in advance.

Do the MAF patch as you stated, but also change the table under Engine Diagnostics:
Set the MAF fail freq to the max it will allow (mine is 16,384)
Set the Diagnostic Tests P0101, P0106, P0121 to higher temps that the car will never see, and set that P0068 RPM one to something higher than your rev limiter. You don't want those to hit. I set the temps at 256F, 257F, and RPM to 8000.
Haven't had that problem since.
