Well known fact the brand of injectors you have are a POS. You said you checked the fuel pressure....how long did it hold after the key was turned off? I'd also be hot on ohming them. Hmmm, I thought 108 was the threshold too.

i bought the car from a guy in new york. he said he had an azzato chip in it. could this be why the blms are at 98. it does have hooker supercomps , ceramic coated. but it doesn't have a heated o2 sensor. i just ordered one from casper electronics. what are the ohms supposed to be when hot? the fuel pressure did not drop over a 2 minute period.

well i think i found my problem. i ohmed my injectors , 6 had 16ohms , 1 was 12 ohms , and the other one was 4 ohms. my next ques. is i have a set of svo blue tops 24lb that was on my 85 vette, will these work without having my chip redone. i do have an afpr. will that compesate for the larger injectors?

Any time you change the size of the injector, whether by capacity or FP, you should modify the calibration to reflect the new BPC. And you'll likely still need to tweak the tune.
