If it can it more than likely can only do the basics and not the A/F

If the A/F is off then theres no way for superchips to fix it so a change of tuner would have to happen.

Shouldn't the PCM be adjusting fuel to hit around 14.7 at idle and part throttle?

the pcm is always gonna try for stoich...but you can adjust fuel trims at idle and part throttle to improve performance. I was able to log my af's (not talking about wb) in closed loop with my old sc 3815...but I know 03's didn't have this option..I was thinking maybe the newer ones did..

That's kind of what I thought. My PCM pulls a ton of fuel at idle, like -20 for LTFT.

if he's on the rich side (I bet he is), he can pull the powerwire and/or use a warmer tstat to lean it out a little bit..

that's WAAYYYY rich...you need to pull fuel ( - numbers are rich, + numbers are lean)... I would pull the powerwire and see what it logs...

That is why I want a custom tune. I need to get some fuel pulled at lower rpm's but not at higher rpm's. The pw is still on bc at wot it is a little lean.

in closed loop (idle and part throttle), the perfect LTFT is 0.0000
