I have a 98 gtp and the mods I have currently installed are a 180 drilled t-stat, fwi, ssac headers, 3.5 pulley, dhp tune, autolite 104's, flowmaster mufflers and at first I was having up to *16 kr untill I installed the headers. Then it went down to *7 kr and I noticed it got alot of kr when I had and ported supercharger and ported lim done. So I was wondering why that ported supercharger and lim caused all that kr and what I should do.......thanks

Probably have a vacuum leak. That and I bet your motor mounts are shot and your front sway bar isn't flipped upside down...and that DP is making contact with the sway bar due to your bad mounts and thats causing false KR

dont need to flip the sway bar with ssacs UNLESS you have the GMPP sway bar.

With false knock does it make it run like crap? Cause it makes my car run like crap in WOT

Sure your not misfiring? And why would you go WOT if something is wrong with your car anyways? It isn't helping it. Any SES lights?Originally Posted by 40mphGT

false knock will cut timing.

I have a friend who uses dhp tuner and he did not say or mention any kind of ses light. However he said I was running lean so he adjusted my maf tables and it helped alittle. So now I have about 6 to 7 kr with only 9 lbs of boost when I have a 3.5 pully

6-7* of KR is BAD.
I'd put the stock pulley back on that thing...or get rid of the false knock that is happening somewhere...headers and a 3.5" in theory is just fine...but something on your car is off.
