I wonder how much more a tune would give me based on my current mods and AFR's?
Of course I would love to have more, but don't want to run it on the ragged edge either.

no track times with the current mods. I went to the 1/8 mile track back in May and ran a 8.3 with belt slip in 80 degree weather.
I have since separated the cooling systems, installed K&N filters in the SL55 boxes and gasket matched the intake.
