DuraMax and Allison performance tuning

4 Levels of power from 30 Hp and 150 lbs ft. to 90 Hp and 250 lbs ft of torque that are set through a routine with the ignition key, accelerator pedal and gear shift lever.

The engine performance is achieved by increasing the duration of the injection and the time it occurs. The power is only available once the engine is up to 80% of the engines operating temperature and is programmed to occur early in the throttle pedal travel.

Transmission monitoring occurs and if clutch slippage is indicated the power is backed down to stock levels and then gradually stepped back in. The power also is backed off when shifting occurs into or when in convertor lock.

The EZ Amp has BD's special custom tuning.

Installation is EZ with factory specified plugs.

High flow air filters are recommended to complete these performance kits.

Maximize the power from your GM Diesel with the chip or computer from BD. This new program will produce a 30-40 horsepower increase and 60-90 lbs of torque. We have modified the transmission shifting to take advantage of this performance increase. On 96-98 models, we program the computer with performance curves and replace the complete computer.

On 1994 & 1995 trucks, we simply replace the E-prom located in the computer mounted behind the glove box. 1992 & 1993 model year engines are mechanically-controlled. Enhance engine horsepower by installing a BD turbo wastegate control, a larger exhaust system, and a higher flow air intake system to increase air flow and reduce exhaust temperatures.
