I just got my 306 dropped down in my 88 gt 5spd. I know it's speed density and we put a mass air on it and a computer for mass air. but my problem is that it wants to cut out sometimes under throttle but sometimes it runs fine. Another thing is that i've heard when ever you put a new computer in a car it takes it so long for the computer to reset itself. Any ideas on what i should do?

 

what is the timing set at? fuel pressure? Did you set your TPS voltage

 

timings set at 12 and i don't have a fuel pressure gauge yet and my tps voltage isn't set yet, we just got a 70mm professional products throttlebody

 

ask the computer what it thinks first.



You may have to drill a small hole in your throttle body plate mid section to smooth it out some
