I've reached the next stage and am ready to mod yet again for HP. The wife ruled out a supercharger for me and I'm not wanting to play with N20. So, I'll be chasing NA power. My current mods are, boss intake, lu47 injectors with e85, clutch, catless x-pipe, pypes axle back and most of the suspension mods. Someday boost will be mine, but in the meantime what would you recommend next? I've been eyeing boss 302r exhaust cams or headers.
