Injector offsets

I have 24lb SVOs and my offsets are at the stock setting. Should I change these to the proper settings for those injectors?

Try stock and the SVO offsets and see what happens. You might find the car runs better with one or the other.

I maybe wrong but I though SVOs were rated at a higher fuel pressure? If so, then the stock 24# would be better.... no?

No. He's asking about the offsets...not the injector constant.

FWIW, I've always had better luck with the stock offsets on SVO injectors.

I understand that, but dont the RP 24# flow better than the SVO 24#s? I read somewhere that SVOs flow less than stockers since they are rated at higher PSI???

It's the other way around. The SVO's are rated at a lower pressure 39.5 (I think) and stock F-Bodies run 43. The SVO's will have higher output at stock F-Body fuel pressure.

Oddly enough, same here. With my injector constant at 31.68 with my 30# SVOs, I get very close to 128 BLMs at idle. If I change the offsets (raise them like they are rated) the BLMs start to take a nosedive... strange.
