Aight heres the deal, I need more hp, but I need to keep my warranty. So I need some bolt ons that will give me decint gains (15-20RWHP) per mod. So far I was thinking the C&L 85mm maf and maybe the hypertech programmer II? Are these worth the price? What about the steeda u/d pulleys, are these easy to install and take off if needed? Also the steeda t/a? Anyone got anymore ideas let me know.
