Not this A/F raito bs that we can do and even then, I don't think A/F ratio adjustments on a car with full bolt ons will really make a difference. Tony at FI kinda proved that when they had cleaned up the A/F ratios when the LTH's were being tested. Everytime I return to this site I always see people talking about how after a tune the gains will increase. This isn't an LS7, it's a VQ. I am supprised to see a lot of F/I set ups running for so long without any majoy issues or at least, we haven't heard of any.
