More power and over 10% MPG increase

This was the last item installed out of an AEM cai, Pulstar Plugs, Rancho Shocks, Helix Power Tower TB spacer. Before the programmer, improvements were hardly noticeable. AFTER the install, on the basic performance mod, power is definitely up, shifts are at better points / faster, and my MPG went from 11.3 to 12.8+ average = 12% increase = HUGE. It's tempremental during install, so do it with tech support on the line. I don't like that you have un program the vehicle before any service.

This is a great addition to any truck. It definitely boosts your power and increases the feel of the transmission. Great for a slight boost in mpg's or just making it run on the right fuel. If you spend the money getting decent gas, you might as well have the engine act like it is getting it.

Easy to download from the disc and update the Programmer for my vehicle. So far with the first tank of gas the mileage has improved about 1.5miles per gal. Runs smoother. Don't know about how it will do with my camper yet but will soon find out in a few weeks.
