Other than gears, a tuner will have the biggest seat of the pants out of any bolt on mod

Support your local speed shop and get a better tune. Get it custom on a dyno.

Absolutely! A Bama custom tune will by far give you the biggest power gain for the dollar, compared to any other bolt-on mods. You'll see an increase of throttle response, HP/TQ throughout the power band, and even possibly 1-2 MPG if driven for economy.

Plus, you'll be enrolled into our Bama Free Tunes for Life program. Which means you're eligible to receive free tune updates for any future mods you add down the road. Including correcting the speedometer for any gear changes, too!

Hope any of this info helps you out. If you have more questions, feel free to contact me!
