thank you guys, i showed my friend the thread so far and hes gettin furious. see i would not have argued with him and just let him waste his money on this product IF it was being put on another car than his FRICKIN 68 MUSTANG!!! man as soon i heard what car he was puttin it on i snapped(me and my dad have a 69 mustang gt, and i hate when people frick up classics like that).
so ya, he'll prob. be stubborn and buy it anyways, but im gonna take ur advice and take him to a dyno, see what happens then...maybe he'll believe me when there is solid proof in front of his eyes, but he is very stubborn so who knows...
thanks for all the info guys..
