Well, I finally have the car out of the garage. I added a Mac cold air intake, 73mm MAs, 75mm throttle body, roller rockers, under drive pulleys, ported and rebuilt the super charger. I also hollowed out the cats. Now the problem. When I start the car it reves up tp 2K and sometiomes will drop back down to 1k after 30 seconds. Is it the voltage on the TPS? Thanks for the help.
