Chip or Not
Hey guy's, I have a 1989 Big Bronco 4x4 stock gearing w/347 stroker kit 9.2to1 comp roller comp cams ,lifters,rockers, ford motor sports mass-air kit installed shorty headers . when I did the motor it needed injector's I bought 24lb injector's & installed a adj. fuel reg. had a hard time to get the engine through state smog insp. I cut down fuel pressure's! Do you know if I need a chip for this engine or not ? Fuel is not smelling rich ! It has stock head's & intake & throttle body. I'm not sure about fuel pressure's that is needed to set the reg. for my injector's
Thank's , Don

A wide band O2 sensor allows you to measure the air/fuel ratio very accurately. A good speed shop should be able to do this test for you and its relatively inexpensive. Proper A/F ratio can do wonders for the power!

You're going to find it hard to pass emissions with that cam. Its really impossible for me to give you any concrete answer without knowing what A/F ratio you're currently running. We can get it in the ballpark assuming you're using a stock fuel pressure pump and regulator, but its very difficult to know the ratio with the aftermarket regular without a wide band O2.
