Ok first off this is what I got
1992 mutang gt
306
Afr 165 heads
Tubular gt-40 intake
Ander son for n-21 cam
30ld fuel injectors
75mm throttle body and egr spacer
75mm mass air calibrated for 30 lb fuel injectors
190 in tank fuel pump
anderson for power pipe

Ok heres whats going on, I just got my car running a little over a week ago and have 400 miles on the motor. To get the car to run and start nicely, I have the fuel pressure at 25 with the vacumm off.{ that seems really low}. Now For the other wierd thing I have the timing set at 22 base timing with pip out thats 42 total advanced. That seems like at alot to me. I cant seem to get the plugs to show me any sign of lean or richness. Also when it first starts it stumbles like it missing and the idle is always surging. I think mybe the plugs arent changing becouse the heads are making the fuel burn so good.What do you think about the fule pressure and the timing? Also what do think about the surging and the stumbling?

fuel pressure should be 41-42psi vac off. start your base timing at 10* and work from there. 22* base is way too much

I know were to start but the setting that I Have it at makes it run deccent but i know thier not right. When the fp is at 45 it hardly starts and also it runs like ****.Timing at 10 degrees it also runs like ****? Iam confused.

Also.. My car isn't any faster than it was with the stock heads and other cam. I installed my cam at 109* when it was recommended to be installed at 106*. Could this be my problem?
