on a random note.. did you know that hood scoops start to make a whistling noise at around 120mph?

it doesnt throw the code, it jsut gets stored in the pcm. when it does throw a code (the p1406), the scanner reads that it recorded the p1270.
the reason the CEL came on is because of the EGR system. Nik, the DPFE/EGR doesnt like race headers. Do the DPFE test and see how the car runs after that. have you noticed any stumbling or hesitation?
