Fuel injectors for a 91
I'm in the market for some new fuel injectors, but I have one question should I buy 21lbs or 24lbs injectors. also I'm buying a new fuel pump, and fuel preasure regulator. 1991 L98 K&N openlid filter. TB air foil, MSD coil & wires, no pre Cats, no water pump disc..

I would get the Ford #24s, theyre cheap and high quality, but use the AFPR to turn down the pressure just a little to help the computer compensate.

Re: Fuel injectors for a 91 (6spd)
Custom chips are not necessary for the #24s. The ECM can compensate by itself for that extra fuel, but, its likely to run on the rich side. So, install an adjustable pressure regulator and turn the pressure down on the Fords to HELP it compensate and it'll run like a champ.
