6.2L Up To 16.3HP and 23.7 lb-ft Torque Gains!

The 2019–2022 Chevrolet Silverado brings modern tech and capability to the table, but factory tuning still prioritizes broad reliability over performance. DiabloSport bridges that gap with advanced tuning solutions designed specifically for today’s GM truck platforms. Whether you’re running the 2.7L Turbo, 5.3L, or 6.2L, DiabloSport unlocks hidden horsepower and torque while dramatically improving throttle response. The result is a Silverado that feels quicker, more responsive, and far more dialed in than stock, eliminating the lag and hesitation that come with factory calibration.


Beyond added power, DiabloSport tuning transforms how your Silverado drives every day. Transmission tuning improves shift timing and firmness, helping your truck stay in the right gear whether you’re towing, hauling, or cruising the highway. Adjustable parameters allow you to fine-tune your setup for your specific needs, giving you more control over performance and drivability than ever before. With simple installation and proven results, DiabloSport upgrades turn your 2019–2022 Silverado into a truck that responds faster, pulls harder, and performs with confidence in any situation.
