Yes definitely! The 3.73's help out too

But I had the tune installed before the gear change and the car felt more powerful. Steeda claims at least 15 avg. rwhp from the tune alone. I'm running very mild intake/exhaust mods. With the adaptave tune once I add a CAI and an x-pipe I should begin to see even more gains.
For the price you cant beat it either. The tune replaces the need for a timing adjuster and a speedcal, all while keeping full diagnostic ablity of the ECU = no dealership hassles.
