The 2.8L Duramax in its factory trim is rated at 180 HP by General Motors. Complimenting the new power plant is

the 6L50 transmission.  Both the engine and transmission use existing powertrain control modules which have

allowed the Motor Ops team to quickly gain access allowing for power improvements. After hundreds of revisions, the

2.8L Duramax and 6L50 trans now meet Motor Ops stringent quality standards. We are confident our new product

will significantly outperform the factory calibration in power, driveability and mileage.  

By working through the engine and transmission calibrations together we significantly widened and raised the factory

torque curve, settling on a peak of 460Ft-Lbs which is very near the rated capacity of the transmission.  With the

wider torque curve, we're able to shift the truck sooner, and engage torque converter lockup sooner without bogging

the truck. The end result is a truck operating in lower RPM equating to lower fuel consumption.  

Tuning on the 2.8 Duramax for the Colorado includes 4 power levels switchable on the fly as follows: 

1. (Optimized Stock +10HP): Power level near stock for towing at or over max GVWR.  Also useful for when

the truck is driven by those who do not need the extra power and torque. 

2. Tow Tune (+32HP/30Ft-lbs): This file is designed to incorporate appropriate power and torque gains for

use when towing.  Greatly improves your ability to get the load up to speed and maintain it on grades or

while passing. 

3. Sport Economy Tune (+45HP / 60Ft-Lbs): A very fun tune that is recommended for daily driving use in

unloaded scenarios.  This tune has a little bit too much mustard for extended high output pulls such as those

you'd encounter while towing.  

4. Performance Tune (+52HP/80Ft-lbs):  No explanation needed.  This is edge of performance balanced with

long term reliability.  Enjoy!
