Hissing sound, need help I have a 98 TA and just installed Pacesetter LT with a TSP ORY. I have checked all the clamps and there are no leaks, i have checked and tightened all the header bolts along with the egr and air bolts, but i am still getting this hissing noise. I only hear it when accelrating,not while idling. I didnt hear it much on the first day, but now i really hear it. I used restrictor plates for the AIR, can the smaller hole be whats causing the hissing/wissling type noise i am hearing, or can it just be an increase in valve train noise? I dont hear any tapping or knocking, it is consistant with the rpms, it's always there, and i have lifted the car and checked for leaks a few times with non to be found. Any assistance would be apreciated. Also, i dont have any vacuum leaks.
