Review on πͺ Revolutionary Performance Chip - Boost Fuel Efficiency, Save Gas and Upgrade Horsepower for Chevrolet Silverado 2500 & 3500 4.3L, 4.8L, 5.0L, 5.3L, 5.7L, 6.0L, 7.4L and 8.1L! by Chris Endricko
Don't expect much. Follow the instructions!
Toss. Just 1.5mpg in daily driving. But got 3mpg when towing. Definitely a little more responsive. I prefer a direct plug system to a plug and play chip.
- Decent performance
