Our files are basic: economy, tow, street and looney. We can basically create the file that you will feel most comfortable with.

* Economy is designed for bumper-to-bumper traffic to reduce turbo lag. We've been told you can save between 2-4 mpg. (40rwhp)
* Tow is designed for pulling. A normal tow file is about 50hp, when aggressive can range between 65-75. We can also add jake brake to any tune, except Looney. This feature works with the exhaust back pressure in your truck.
* Street is designed for highway driving. It's driveability parameters are intensifed for ease in passing and maintaining higher speeds for longer periods of time. (90-120rwhp)
* Looney is designed for city driving and the track. It is the highest race tune that we will send via the net without physically tuning your truck. (130-160rwhp)
