I installed the Gibson dual exhaust a few months ago and I’ve been real happy. This weekend I installed an aluminum air box from CFM Performance. I’m running the upgraded Donaldson air filter. With the combination of the air box and exhaust will I need to install a tune?

No, but I would recommend it anyway. Do watch your EGTs though, because these already run pretty lean. I went with the AA stage 1 tune and it’s much more responsive with the throttle remapped and torque limiters removed. Makes driving more enjoyable all around, even though it’s not adding any HP.

But expect increased fuel burn. A stage 2 AA tune nearly doubled my fuel burn. It can make a big difference when you're a loong way out. Talk to Mike about your needs @ Aftermarket Assassins. He's very well respected.
