Time to autotap and see how rich you are...then you might be able to use a MAF translator to adjust it and straighten it out :cheers:

Re: running rich (NJVetteGuy)

MAF Translator is a PITA.

Running rich is very common when air flow exceeds the expectations of the stock programming.

Much better off tuning with Ls1Edit, AutoTap and Dyno

Re: running rich (pdd000)

How do you know it is running rich? I am curious because I just installed FLP's and have no codes or other evidence that it is running rich. Won't the long term fuel trim adjustments eventually compensate?

Re: running rich (alc2001)

i thought i might be running rich because of the excess carbon coming out of the exhaust and water too :eek:

Re: running rich (pdd000)

Now that you mention it, I have noticed some sootiness in the exhaust tips. Before the headers, the exhaust ran ultra clean. Hmmm. Sounds like time for some Autotap/Predator/LS1 Edit investigation. :yesnod:
