Description:

The GM 8.1L UltraPower ECM has long been the ultimate performance modification you can make to your GM 8.1L powered RV or truck with the highest power gains on the market! Thousands of satisfied customers have reported fuel economy increases as well as less transmission downshifting because of the increased horsepower and torque. The UltraPower ECM performs very well on both stock engines and ones that have been upgraded with other modifications.

What sets us apart from the others? Banks even admits their handheld AutoMind only changes one parameter within the computer, whereas UltraPower changes approximately 400 parameters. That is the difference between cookie-cutter and custom!

While most tuners rely on “canned” tune files (not custom), our GM 8.1L Custom Tuned ECM is tailored specifically to YOUR vehicle. We require the VIN so that we can pull up your vehicle’s specific parameters and create a truly customized tune for your vehicle.


UltraPower 8.1L ECM Benefits:

  • Fuel mileage improvement of up to 1 MPG
  • Gains of 50-60 Horsepower and Torque Gains of 70-80 lb-ft
  • Maintains speed and higher gears when climbing hills
  • Improved throttle response coupled with more power makes driving more enjoyable
  • Includes a datalogger that you plug into the OBD2 for us to analyze and optimize engine efficiency and performance
