EFI live is the way to go if you can find a tuner close or through the internet, my rc/lb went high 13's/low 14's on tune, intake, exhaust, lift pump, and shimmed fprv. That was pushing it on stock trans though because it went less than a month later. If you go tuner or efi live you should look into the mods i just listed, they are well worth the $
