Diesel Tuner's Blog

We've logged thousands of miles on our 2.8L Duramax Canyon - hundreds with a 5,000-pound load.  We continue to find this medium duty diesel worthy of a closer look.  When combined with DuramaxTuner.com calibrations you'll discover it can be incredibly fun and responsive to drive.

After all the 2.8L diesel Colorado and Canyon trucks we have tuned you might think we would get bored with them.  In reality, it has had the opposite effect.  Every time you drive one of these it's hard not to be impressed with it.  The seats are comfortable, interior is well equipped and because it's such a light truck (compared to the 3/4 and 1 tons we usually drive) it feels nimble.  Especially when you have the SPADE with DuramaxTuner.com's custom calibrations.

You might like the 2.8L Duramax Canyon/Colorado if:

• Your truck is used mostly for commuting
• When you tow, it is something lighter than 8,000lbs
• You want to best possible fuel mileage from a vehicle with a truck bed

2.8L Duramax Tune Loading Instructions

The 2.8L Duramax in its factory trim is rated at 180 HP by GM and carries a full compliment of emissions equipment to keep it clean and quiet.  Backing up the new power plant is the 6L50 transmission.  Both the engine and transmission use existing power train control modules which have allowed the team at Duramaxtuner.com to quickly gain access and make improvements.  Over the past several months, we've worked with our customers and on our in-house truck, to develop and test tuning for this platform.  After hundreds of revisions, we're happy to have a product that significantly outperforms GM's 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.  This means less operating RPM and ultimately lower fuel consumption numbers.  Best of all, these calibrations work without any other modifications to the truck, meaning that you still get a quiet, clean, smokeless truck that can be returned to stock at any point.
