The new Chevy Colorado comes with an optional high-output tune for the 2.7-liter turbocharged engine that can be tuned for more power. If you want more from your Colorado, here’s what you need to know.

For the 2023 Chevy Colorado, the 2.7-liter engine comes in actually three flavors of power output with Turbo, Turbo Plus and the Turbo High-Output tune.

Chevy Colorado high-output tune

More powah is always a good thing, right? We thought so after our first drive of the 2023 GMC Canyon, which comes only with the Turbo High-Output tune — unlike the Colorado I drove with the Turbo Plus option.

The high-output tune adds 40 pound-feet of torque to the engine. This may not seem like much, but it really does feel faster off the line.

How to get the upgraded tune

With the new truck and the tune, there has been a lot of discussion online about how to actually get the tune done. I’ve heard from numerous people who have gone to a Chevy dealer and left empty handed.

If your Chevrolet dealer is telling you they don’t know how to do it, here’s the deal.

First, be sure you have an engine with the RPO (Regular Production Option) code RWQ. This designates the truck has the L3B engine and can be tuned up for more power. Keep in mind the WT and some LT engines can’t be tuned due to not having the mechanical parts.

Next, the tune is available through part number 86577457 according to Anisha Sredzinski, Chevrolet Trucks & FSSUVs Communications Manager.

Sredzinksi says there isn’t an actual part per se, it is really just the way dealers can put it into their system to charge consumers for the tune.

The price should be $395 for the tune.

The bottom line

New trucks always cause some confusion with new features, and the Chevy Colorado Turbo High-Output option is certainly part of this confusion. Hopefully with this part number, you can help your dealer understand what they need to do.
