I see many cold air induction bolt ons that state 10+ hp without a tune. Even some of the mags state a dyno increase without a tune (Airaid). I don't want to tune to stay under my warranty and don't want any question of the engine develops issue later
I have a 2011 GT 5.0
What is the best one without re-tuning that you have seen/heard of?
Thanks
