okay so ive installed bings intake manifold, all is good but shes running really lean. now im guessing this is because of the extra air its getting now. ive done a boost leak test and there are no leaks in the intake system. i have an safc 2 not installed yet, my question is can i safely tune my car wit this, or do i need to get some other management program… my car is a 1990 with redtop sr, with front mount and bings manifold, everything else is fairly stock on the motor. the car stays lean till i step on it( not full punch cuz i dont want to damage anything) which then it only goes to stoich and drops back to lean, never enters rich. any help on this is greatly appreciated.
ive got a wide band, now wit the safc 2 am i going to be able to correct my fuel and have it run like before the intake mani install, just curious cuz dont want to waste my time installing the safc and have zero success…
just 8 psi for now till i get this settled,then i run 10 , and my fuel filter is new, as for fuel pressure it should be fine cuz the car was running good before the intake swap, are you saying that with adding the manifold it wouldnt make the car run lean? I am just figuring that its running lean because the air is getting to the engine faster; but who knows? also if this helps my timing is right on, brand new coolant temp sensor, new knock sensor, newer tps, and just a regular maf( not the 300zx one, but could consider doing that to), also what you mean by restricted exhaust? let me know on what you guys think.
