2006 H1 Alpha Duramax Xcelerator

Features: Application: 2006 H1 Duramax diesel engines.
Product Description: Once again, for your biggest power, PPE developed the H1 Alpha Xcelerator. This unit is designed to work with the 2006 H1 Hummers with the Duramax Diesel.
Features of the H1 Alpha Xcelerator include up to an additional 280hp, speedometer corrections (for tire sizes ranging from 25" to 44.75" in ¼ increments, and/or gear changes from 2.23 to 5.13), governor removals, and seven levels of performance.
Program levels 1 thru 7 will remove fuel (defuel) from engine during shifts as needed to keep an un-modified transmission from slipping.
In addition, the H1 Alpha Xcelerator raises the rev limiter to 3,800RPM. This unit also retains the stock program so that the truck can be put back to the original settings if the need arises. The H1 Alpha Xcelerator increases the efficiency of the vehicle, which increases fuel mileage (2-3mpg on average). It also defuels for upshifts and down shifts in order to allow transmission to engage into next gear without the need for extreme transmission modifications.
In addition to being an all-star in the world of performance, the Xcelerator is also capable of reading and clearing Data Trouble Codes (DTC) through the OBD II port. H1 Alpha Xcelerator can reset the Allison transmission for Fast Learn operation to begin.
In order to insure that you are getting the best product available, we have tested this product off-road, in the desert, the ¼ mile drag strip, the Rocky Mountains , and in the dyno room. You can also stack the Duramaximizer, Propane, and/or Nitrous with the Xcelerator for even greater results. Take a look at the charts on the next page to see what this product is capable of doing.
(Note: This unit delivers extreme horsepower and torque. Upgrades to the drivetrain are highly recommended!)
