Not Ranked
Timing seems to be making a big difference on my car...........especially with the ethanol in the gas now.......at least in my area. So I backed off to 30 degrees, from 32, which my builder initially recommended. Then he called me and told me to back it off to 30.
With octane booster and whatknot I can turn it back up no problem, but with the lousy gas in my area............
30 miles from me I can still get 94 ultra, but my local stations only carry 93 now with ethanol.
