3.23's to 3.73's I have a stock 02 z28 and I was wondering if I have to buy a programmer after I switch gears from 3.23s to 3.73s to recalibrate my speedometer? or can I just take it to a shop and get this done? and is there anything else I'm gonna run into when switching gears that I should be ready for?
