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

Colorado - Canyon Diesel Dead Pedal

The 2.8L Duramax in the Colorado and Canyon is a great engine!  Overall they are great trucks! 

They get even better once you fix the biggest complaint about them: the Dead Pedal.

 

Let's say you're driving your new Canyon 2.8L fresh from the factory, no aftermarket tuning. You want to pass, so you step on the throttle, and wait, and wait.

The turbo charger has to lead the charge. There's a transient response rate. The delay in that transient response is the dead pedal.

The dead pedal delivers less power than the driver anticipates. The untuned 2.8L feels like there's a tennis ball stuck behind the pedal.

 WE CAN ANSWER THAT

Why tune a 2.8L Duramax?

Tuning for the 2.8L Duramax

 

The 2.8L, 4 cylinder Duramax was released to the North American market in the 2016 Chevy Colorado and GMC Canyon.  This small truck offers a few note worthy features in the diesel powered configuration.   

Features like a luxurious interior make it nice to be inside the truck.  Comfortable seats, a fancy dash, and other little things in the cabin make an impact on driver experience.  Although for you, the MPG rating and impressive towing capacity is what really sold you on the truck.  22 City and 30 highway is outstanding for anything with a truck bed.  

Towing and payload is higher than usual on a  small truck platform.   7,000 lbs is more than enough for your race car, small/medium boat or travel trailer.  

 

Sounds great so far, so why tune a 2.8L Duramax?

2016 2.8L Duramax Tune Loading Instructions

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.  

 

Below are the Tune Loading instructions for the DuramaxTuner.com 2016 model 2.8L SPADE.  If you would like help over the phone, feel free to book an appointment with me, and I will be available when you call.

DSP4 Switch for 2016 & 2017 2.8L Duramax

Switch-on-the-fly Tuning with SWITCH for Colorado/Canyon with 2.8L Duramax:

 

For may years the 2001-2010 Duramax powered Silverado's and 2006 - 2016 Cummins powered Rams have enjoyed the benefits of Swith-on-the-fly tuning.  The switch allows diesel truck owners to change tunes instantaneously while driving.  Making life much simpler for those who use their truck for multiple purposes.  This luxury has been envied by other diesel owners who have to plug in a programmer each time they want to change power levels.  Some truck owners with non-switchable tuning have even started leaving trucks in the hottest tune while towing just to avoid the hassle of flashing in an appropriate towing tune.
