A tune is a reprogram of the truck's engine computer (ECU) that adjusts fuel, timing, and shift settings, changing how the engine behaves without swapping any physical parts. This one comes preloaded on a handheld SCT-based device with multiple tune slots.
why this one — 5 Star builds this specifically for the 2014-2018 6.2L (both Chevrolet Silverado 1500 and GMC Sierra 1500 confirmed), not a generic multi-engine file. Note: the 8-speed-equipped trucks may need a separate TCM unlock.
Dale's Super Store listing states the tuner "delivers a boost in both horsepower and torque" via its Performance/Tow and Performance tune slots but does not publish a specific number.
Not legal for sale or delivery in California.
