Sorry guys I know this question has been beaten to death but I just want to know what people are gapping there NGK TR6 spark plugs. Im running 6 psi for now with a vortec FMU
Awesome dude thanks for the quick response, any more last minute things I should be aware of, im only running the FMU until I get a emanage and some dyno time should this be cool (by cool I mean relaible)
