DuramaxTuner 2.8L Duramax Single Tune Spade (2016-2020)


Unleash more performance from your 2016-2020 GM Colorado/Canyon 2.8L Duramax with the Duramax Tuner 2.8L Single Tune Spade Tuner. The 2.8L comes out rated at 180HP by GM, complimenting the power with emission equipment to keeping it quiet and clean. Coupled with the 6L50 transmission, it's a mean machine. The team at Duramaxtuner has perfected engine and transmission calibrations on this platform through meticulous R&D, in-house tweaking and on-road driven results. For two years now, their 2.8L tuning has been proven to improve your stock calibrations with more power, better drivability, and higher mileage.


Through adjustments via engine and transmission controllers, Duramaxtuner was able to significantly widen and raise the factory torque curve. By widening the torque curve, your truck shifts sooner and engage torque converter lockup quicker without bogging down the truck. This equates to less operating RPM and ultimately lower fuel consumption numbers.  To add to the impressive gains made with tuning, you'll be shocked to learn that no modifications are needed with the Spade. This means you still get a quiet, clean, smokeless truck that can be returned to stock at any time. 


This tuner holds 1 tune. You have 3 tunes to choose from, they are as follows:


Optimized Stock (+10HP) - Power level near stock for towing at or over max GVWR. Useful for when the truck is driven by those who do not need the extra power and torque.

Tow Tune (+32HP/30Ft-lbs) - This tune 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. Duramax Tuner advises against towing with this tune.
