Description:

UltraPower Custom Programming for the GM 8.1L 496cu has long been the ultimate performance modification you can make to your Workhorse/Chevrolet RV or truck with the highest power gains on the market, at the best price. Thousands of satisfied customers have reported fuel economy increases along with the addition of the extra pulling power when tackling steep grades. Also, less downshifting will occur as a result of the increased power. UltraPower Custom Tuning works very well on both stock engines or ones that have been upgraded with Banks Power Systems. 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.

Applications:

  • GM/Workhorse 8.1L Engine
  • GM Trucks/SUV’s with 8.1L Engine (May require Passkey and Crankshaft Position Relearn Procedures)
  • Workhorse Motor Home Chassis from 2001-2011
  • Kodiak C4500/C5500 Chassis with 8.1L

Benefits:

  • Gains of 50-60 HP and 70-80 lb-ft TQ
  • Gains of 1/2 - 1.5 MPG
  • Downshifts less approaching hills
  • Improved throttle response
  • Improved acceleration for merging onto freeway and passing vehicles
