I have put hundreds of hours of work into my 94, gt this winter.. i am having a huge problem. I did edelbrock performer II upper and lower, edelbrock 70mm throttle body, bbk cold air with granatelli maf tuned for cold air and for 30# injectors. also i did an aeromotive adjustible fuel pressure regulator and a 190 lph fuel pump.. msd 6al box, msd distributer cap rotor and 8.5mm wires. and a bunch more.. in the stock ecu i have a jet performance chip. i dont think the jet chip can handle the maf and the 30# injectors.. the car runs like absolute crap.. i checked all the plugs regapped them.. it had old gas in it. i filled it up with 93 ultra thinking that was it... a company called motorvation wants $400.00 to reburn me a new chip... and if i get a set of heads and a 347 which i plan to do i will need a new one another $400.00 is there something i am over looking????

are u running 30lb injectors with stock heads and cam? if so thats your problem why did u get thoes injectors?

cause i plan to supercharge it in the future, i figured i could tune it down with the adj fuel pressure regulator... yea cam and heads are stock

you will feel the mods if you put heads and a cam in.

i have an extra engine i am building up to a 347 stroker and i wanted to have everything switch over when it was done, do you think its them , i hope not cause i already installed them and the maf

30# is waaaaaaaaaayyyy too much for stock cam and heads. Good luck tuning down. Your car isnt going to run right. throw the stock injectors back in and recalibrate your maf

its brand new how do i recalibrate it? it dosent even have 1 mile on it and neither do the injectors

sry bud but all i have to say is thats dumb, how come u did not wate till u put the other motor in? now u have to spend another hour+ putting the stock injectors back in.
