Effective immediately, as of July 3, 2022, all custom tuning done by me via HP tuners will be locked. If at any point you would like to have someone else tune the vehicle, I will gladly unlock the ECM and remove my file at no charge.
For those currently running my tunes, I ask that you please allow me to remove the file from your vehicle if you so choose to have someone else tune the car.
I apologize for any inconvenience this may cause you, but it is a measure that needs to be taken.

Thank you to all of our loyal customers, and have a great holiday weekend.

With the race season coming to an end, after a bunch of thought, we have decided to offer 2.2/2.4 ecotec tuning for circle track cars and circle track cars ONLY. (No street use)
Brendan has spent the season dialing in and perfecting tunes on multiple cars that have been extremely successful (multiple heat race and feature victories, including Owosso Nationals, as well as having the 3 fastest Ecotec cars at Michigan Cup last weekend)
Pricing will be subject to how far you, the owner, would like to go. Initial cost will include a base file and an hour of dialing in the car.
Shoot us a message with any questions you may have.

Absolutely MASSIVE L5P oil cooler for Cody’s race truck. This cooler is 100% larger than a factory oil cooler for 01-16 trucks (literally double). This will help keep oil temps down for hard street driving, warm days at the track and could also help with oil temps in heavy towing (just not in this application)
