Ok, does anyone have their own bin file for an almost stock LT1 they might want to share! I need to reprogramm for gear ratio and a few other things on my LT1, I have tunercat but have no idea how to use it yet, and I have a PC, not a laptop, and I do have the OBDI cable. So just chaning injector size to 27 will make it run better? What about Brian at pcmforless to do a $50 "load yourself" bin file for a baseline, or should I just try to get my own? Thanks.
