you dont HAVE to get a tune, i dont have a tune and im putting down 342/362 to the wheels. and running 12.4's @ 113mph on street tires & stock gears, cutting a 1.97 60'.. bolt ons only. im sure a tune would help but as far as it being imperative after the header install, no, youll be fine w/o it for a while. I would look into asking chummma, he did brandons car and robs car, and will most likely be tuning my car in the future
