Newbie question I just received Tunercat for my '94 Z28 last Friday and I'm new to tuning, so here is my first tuning attempt. Question: Which table to I use to richen during WOT? Do I increase the injector pulse width? If so by how much and up/down to richen/lean?
My car is running a little lean around 5000-6000 after my cam install. This is also with PCMforless's tune, so the tune should be almost right, but it just needs a little tweaking.
Thanks in advance

Mid lengths headers, CAI, 209/217 .498 .517 112lsa. stock 24 lb/hr injectors. I just noticed that my injectors are set to 25.48 lb/hr in the pcmforless tuning??? Is thissomething that is usaually done for a tune? If I set it back to 24 lb/hr would my car run leaner?

I think think that will fatten them back up actually, mine were set for a 26# and it was running rich, when I set them for the 30# it leaned up so I guess it would work in reverse, try it, keep a datalogger on it, and if it starts going lean shut it off and reverse it.

Unfortunately I don't have a datalogger, but I've been going off my a/f gauge. I'll probably wait till my car's on the dyno to make the change, that way I can check the a/f on their wideband.
The question still is, though, Which table to I change to richen/lean a/f at WOT?
