Got my car dyno this weekend at Performance-Dyno in Concord, NH. This wasn't my first time on the dyno, but the first time that I got my A/F numbers. You can see my numbers in signature. My question is: does anybody else running a Delta Chip know where their A/F numbers are ? My car is running alittle lean around 14. And I actually pulled better numbers when I switch the chip off and my A/F dropped back to 13. Should I get my chip reburned ?
