Our performance computers are based on dyno testing and street testing, giving the best possible tune for those than take care of their vehicle. Improved spark and fueling based on application/octane, and improved shift points and line pressure adjustments for the 4T45 and 4T65 equipped engines. Coolant turn on times set closer to the thermostat to keep the engine temperature more consistent as well. We offer emissions delete for racing, and speedo corrections for aftermarket wheels. We can also change the tune for some modifications, so give us a call or shoot us an email for any questions regarding our tuning capabilities.
We no longer use a core system, and most of our customers prefer to keep their stock computer for backup. You can send us your stock computer, a compatible computer, or choose the option to have us source one for you. If we are sourcing the computer, we will need to know both the VIN, and the SERV# on your stock computer. If you are sending a computer that is not original to the vehicle, please make sure the SERV matches your original and give us the VIN off your car. You can add a note with your order, email us at sales@wot-tech.com, or call 574-968-7607 to give us more information on your setup.

Filling out the order form
If you want to change the rev limiter in gear or park/neutral, enter the new values here. Otherwise 0 will keep it stock. If you have a cam and we are raising the shift points, the limiter will also be raised to match automatically.
SERV # is found on the PCM itself, and helps assure the replacement is going to match. If you are sending your original computer, SERV is not needed here.
VIN helps us verify the application and all of the details in the tune for a starting point. If you are sending your original computer, VIN is not needed here.
Additional Info is for what kind of use the vehicle is for, modifications to the motor, transmission, and a change in tire size could be put here.
Contact us if you have any questions. There is a 30 day money back guarantee on all WOT-Tech PCM tunes.
