i have a 01 ls1 with long tubes and a cold air intake. custom dual 3" exhaust. i also have sped inc fuel rails. @ wot my aem wideband is reading that the air fuel ratio is 10.0-10.5. is that normal? i have fuel pressure set to 58psi. ive heard that with the lth's it would run richer then it should but in the 10's?

Back when I had my wideband on I would run 12.5-12.7 @WOT and I had longtubes, cai, and a tune back then. I deffinetly think you are too rich, whats it read at idle and cruising.

idle and crusie are usually between 13-15~. although sometimes my idles shows very lean and then will go back to 15. do you have any idea what your wot was b4 u had a tune?

I had a tune before i had the wideband, but I drove around without a it tuned for the longtubes and the afr was right around the same.

You need to get it tuned with LTs, that'll solve your AFR issue

i understand that. my main question is that is it typically that rich. "in the 10's"
