leave it non rfg... if you remove the rfg "tune" the car will run leaner... while lean = power ... too lean = knock knock knock .....

the HPP3 power programming leans the car out already... if you have ported MAF ends, you're even leaner ... add the RFG tune and you're even leaner

(I believe the RFG tune was based on where the car was to be sold.... being commiefornia they prolly employ some type of super RFG that will soon spread throughout the country )

do you have a scanner/logger? what mods do you have on the car right now? (IMHO the HPP3 is only good for changing shift points, fan settings, and gears ....)
