Just installed new trick flow heads, trick flow intake, 1.6 roller rockers, 70 mm throttle body, 75mm pro m mass air, 24lb injectors, 255 lph fuel pump, fuel pressure is at 42lbs. Timing is at 16 degrees. The car runs good at half throttle and when its at about 35mph I will hit it at WOT and it takes off like a bat outa hell, but when i floor it off the line it like goes nowhere and really bogs down. It runs worse then when the car was totally stock. I've notice that my idle will seem to go up and down alot on its own and the fuel pressure will move from 40 to 50 psi sometimes on it's own. I've been trying to tweak different things but nothing really seems to help. Do you think the car needs to be professionally dyno tuned with a custom chip. Any advice would be greatly appreciated.
