[ALRAJHI]

Hello guys
i have a proplem tunning a 2001 C5 vette after installing some performance parts (cam, rockers,headers, and crank pully)
the car will run on the dyno at wot lean with 75% tps until 5000 rpm then it will go to 100% tps and the fuel will be just fine.
can you help me guys with this problem please.

make histograms for TPS vs dyncylair and MAP vs dyncylair. TPS vs RPM and MAP vs RPM help too. then you know what to do when playing with PE triggers.
