The short answer is no, you don’t have to do that. The Jeep will run just fine without any tuning – that’s the beauty of modern-day gear. At the same time, if you do already have a tuner/programmer, it would be wise to use it to re-calibrate some settings. This will give you some extra HP and maybe also improve the throttle response (acceleration). But, again, buying an expensive tuner just for a new intake kit won’t be a reasonable investment.
