alright, im selling the mustang (trading in) and getting into a g35 and the dealer wants it with everything thats on it, but what he doesnt see he doesnt know. i wanted to take out the diablo chip and try to sell it, and i was wondering if thats an alright thing to do, i believe its a general tune (exhaust, cai, throttle body was all i had at the time).....if so what can i look to get for it?
