for some reason my car is running really lean, it is very quiet and doesnt have much power. Its a 92 lo3 shortblock and cam with 081 heads tpi intake and a 88 305 tpi tune and ford pink injectors (about 22#s). Ive checked tps and tried a couple different o2 sensors ive unplugged the maf and doesnt really make a difference, fuel pressure is very steady at about 38 with vac. what else should i check

are they pink or yellow orange? i have the yellow orange injectors and they are 22# and work like a champ. the pink ones actually flow more from what i can find but i can't find that model for sale anywhere. the orange ones are 19# on a mustang and 22# on our cars because of the difference in fuel pressure. but then again you are running a lower pressure. try bumping the pressure up to about 43 and see what happens. my guess is you'll be pig rich but that is the pressure a tpi runs stock. you'll probably have to tune the difference out to get it dialed in correctly

they are the pink ones. the fp is correct for tpi but i have bumped it up to 42 and 50 psi but it won't get richer.
