Let us use our years of tuning experience to create a mail order tune for your Gen IV Full Size Truck (models listed below). Our performance tuning for the V8’s typically yields 15-40rwhp depending on your modifications, and usually 1-2mpg increase as well! We spend a lot of time working on the part throttle performance also, making the truck much more responsive and efficient. We can mail order tune for almost any set up, and take advantage of any modifications you may have added. We also fully tune the transmission, including speedometer recalibrations, torque management, shift firmness, and shift points. NOTE: Some trucks will have a separate transmission controller that needs to be send in as well. If your truck has an E67 or E38 PCM (click HERE for pics) you will also have a separate transmission control module. If you have a six speed transmission, the T43 controller is part of the transmission, and will not be able to sent in for tuning (we can tune it in person or with HP tuners). One of the best bang for the bucks for a full size truck! After placing your order, please fill out an order sheet for your vehicle (here). Currently we are not offering a core program, so you will need to send in your PCM to us at 618 Oak Ridge Farm Hwy, Mooresville, NC 28115.

We can tune for whichever octane you like, but premium is highly recommended as a lot of trucks will spark knock with the stock spark tables. Using premium will help us obtain the most power and gas mileage possible!
