Welcome to DF.

You'd get more help if you posted in the right section. I will move you there now.

You should read the Plenum Thread at the top of the 2nd Gen Tech section, could be part of the problem.

 

+1 with Stewie. Also if you are running 35" tires or bigger with stock gears that will suck your power away like nobody business.
