A $395 Dealer Tune Gives 2023 Colorado Models ZR2 Power Without Affecting The Warranty

Trucks / 11 Comments

Chevrolet's all-new mid-size Colorado truck comes with several power options from its 2.7-liter turbocharged 4-cylinder, but an option has appeared on the truck's configurator that allows people to upgrade the mid-range power output to the high-output specs on the ZR2 model.

The Work Truck (WT) and LT trims come standard with the base 2.7-liter engine, which produces 237 horsepower and 259 lb-ft of torque, but you can upgrade the trims to the Turbo Plus version making 310 hp and 390 lb-ft of torque.

The Z71 and Trail Boss have an upgraded engine, but the off-road-ready Colorado ZR2 gets a different tune to make 430 lb-ft of torque while retaining the 310 hp. However, you can option ZR2 Turbo High-Output power with a dealer-provided tune for $395.

It's a great move from Chevy as not just ZR2 owners will want the Turbo High-Output engine.

The upgrade is available for trucks only outfitted with the Turbo Plus engine, so it's a simple option for the Trail Bus and Z71 trims.

WT and LT buyers will have to upgrade from the base engine to the Turbo Plus engine to get the tune added. Unfortunately, if you go with the base engine, you're stuck with it. That's not just an arbitrary decision, though.

The base engine lacks a few essential features used to create the extra power and comes with a cheaper, smaller, and lighter transmission with different gear ratios that aren't rated for the extra power. Or, as Chevy explained to us, if you tuned the base engine to full power, the transmission would terminate itself under the added stress. That's if the pistons don't fail first.

This means you can upgrade any Colorado trim to full power, and if you really wanted, you could snag an absolutely basic WT truck, complete with steel wheels, and have it make full power for just under $32,000. That sounds like one hell of a midsize workhorse to us.
