i have a 1998 gt, pi head swap, livernois cams, stock plenum, injectors, air tube,i also have long tubes, my question is what injectors do you recommend i go with, and do i have to change the maf sensor also? any help would be appreicated, thanks!!!!:SNSign:
Theoretically, 19#s should be satisfactory for your combo. To know for sure, you'd need to get the car on a dyno with a scanner and put a WB O2 sensor in the exhaust. If the WB indicates the car's going lean (and there's no faults to explain it) and/or you find the injector duty cycle is unacceptably high, then you'd probably conclude the need to bump up the injectors to, say, 24# units.
What sort of power are you making now and do you have a WB on it?
