im thinking about future mods for my car and i really want to do a 2.7 pulley with 60LB injectors and a stage 2 belt, also i really want to do a meth kit for a nice cooling mod adn that will add a nice amount of power too. now do you think i should just buy the pulley upgrades wehn i get the money cause that requires a tune and so does the meth kit, so who thinks i should jsut save the moeny for both and get them tuned together? i also have som guages id like to have them installed as well how much am i looking at?
