I raced a GTO and i turned up my boost to 18 with the properfuel had no kr on the ultimate and i ran good all the way from 60 to high Over drive then i pinged for the first time so bad that it choked out the motor. After that i couldnt build up boost past 8-9 psi and i tryed reseting my computer by pulling the ecm fueses went to put them back in and now everytime i start my truck it almost dies intell about 30 sec of running and now sertain rpms it cuts out and i can only build up 7psi in 1st gear. I tryed a new TPS sensor and that didnt change anything. Oh ya i had my cruise control set on flat ground and it started to accelerate?? Im so lost i dont even had a check engine light? This sucks i think an xtreme s-10 would beat my truck right now.LOL
