Livernois motorsports has brought our unparalleled experience with direct injection performance experience, to the new 2014+ silverado, both with the 5.3 ecotec3 and the 6.2 ecotec3 engine chevrolet silverado, and gmc sierra. We began working on improving the throttle response, and overall driving dynamics of these trucks to be much more responsive, and of course improve the shift feel, and performance level of these great engines.

The end result with 93 octane tuning was an additional 27hp and 47tq gain over stock on a 6.2 truck, and 29hp and 34tq on a 5.3 truck. Combine these gains with our proven transmission programming enhancements and the transformation you will notice a complete transformation of the responsiveness and performance of your truck. Add our available cold air intake for added gains of over 10hp and 20tq on both engines for even more performance.
