You wouldnt happen to have a copy/screen capture/anything of what your injector offsets looked like with the 75's would you? A .bin would be nice, but I most likely wouldnt be able to open it as I use LT1edit.
I agree, problem is bigger injectors just wont work well at very small pulsewidths. Dropping the fuel pressure a bunch isnt a solution either. Staged injectors is the way to go but a little pricey for most

I use a bigstuff3 and its just a single line for the offsets, not like the stock PCMs use. I have what I used for the low-z injectors on the stock PCM with a converter box somewhere if thats what you are looking for.

I'll be careful about the altenator belt Thanks, at the least its gonna help me get my idle fueling in line untill I get it on the dyno. Its pig rich right now...
Once its on the dyno, it'll be outta my hands and up to the tuner to get it right.

Thanks KP, that's probably gonna save me lots of hassle.
