Review on Enhance Fuel Efficiency and Boost Performance with our Cutting-Edge Performance Chip/Power Programmer for Chevrolet Suburban 5.3L, 5.7L, 6.0L, 6.2L, 7.4L and 8.1L - Save Gas, Increase MPG, HP & TQ! by Charles Quinones
No performance gain.
I liked how easy it was to install. It was very fast and I followed the directions carefully to maximize performance. (Not easy as a good spell requires the vehicle to be turned off.) I did it anyway. But as soon as I hit the gas pedal, I expected great things that never happened. I couldn't see any power increase or fuel economy improvement. :( Bad investment for me.
