Tuning question.
I just dynoed my car after adding a small cam and ls-6 intake. I am very happy with the SOTP difference and the numbers. My big concern is the AF ratio of 14.6. Is this too lean? I didn't see and knock retard on the graphs, but I thought 13 was the number that worked well. Also, will the car learn the new set up and try to richen up? Any comments are appreciated.
Thanks,
Don

Re: Tuning question. (Malibu Vette)
A 14.6 A/F ratio at WOT is too lean. This is what it should be for good fuel economy and best emissions. Like you say, it should be closer to 13. I think you need a custom tuning job done.
