The Duramax Tuner 2.8L Spade Tuner ramps up the performance in your 2016-2018 GM Colorado / Canyon 2.8L Duramax. The 2.8L Duramax in it's 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 powerplant is the 6L50 transmission. Both the engine and transmission use existing powertrain control modules which has allowed the team at to quickly gain access and make improvements.

Over the past three months Duramax Tuner has worked with their in-house customers and their shop trucks to test and develop tuning for this platform.  After hundreds of revision Duramax Tuner is happy to have a product that significantly outperforms GM's calibration in power, driveability and mileage.  

By working through the engine a trans calibrations together they are able to significantly widen and raise 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 they are 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.  

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

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. 

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. 

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.  

Performance Tune (+52HP/80Ft-lbs) - No explanation needed.  This is edge of performance balanced with long term reliability. Enjoy!

  • Up To +52HP & +80 Ft-Lbs. 
  • Custom Tuned To Your Vehicle
  • Optional Trans Tuning Available

Great power increase for the 2.8 duramax. Awesome performance gains
I got this tuner with the tranny tune about six months ago. Best money ever spent on mods for any vehicle I have ever owned! (I'm pushing 60) Has worked flawlessly. Outstanding power gains especially for towing. After I lifted my truck 3 inches and put larger tires on it, DT sent tune to correct speedo. Great product and customer support.

Questions and Answers

Is this programmer detectable by dealer?
View Staff Answer 
A dealership can sometime detect changes to the vehicle, but they cannot prove exactly what’s been done to the truck. Keep in mind - Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C))
What range or average gains in Mileage have you seen?
View Staff Answer 

It really depends on your driving habits and the conditions of your vehicle to see the best gains in MPG.

Does this programmer have the capability of adjusting for bigger tires(speedo and trans calibration)?
View Staff Answer 

Yes, the Duramax Tuner 2.8L Spade Tuner can be calibrated for larger tires to adjust the speedometer.

What steps are needed to remove Spade before going to the dealer - and what about the DSP4 switch?
View Staff Answer 

You simply use the handheld to change the tune under the Tuning Tool menu from the main screen. This will allow you to change from one tune to the other as well as return the truck back to stock. (The DSP4, once installed, allows you to easily switch these tunes without needing the Spade Tuner plugged in.)
