Comments about Hypertech programmer for 2011 Ford Expedition

The directions lack detail about when and when not to connect the programmer to the computer for updates and or trouble shooting. Causes many DEC's when programming the car but none seem to effect the download to the car. The car seems to run smoother. Overall a decent buy.

Follow instruction closely, be patient with updates and registration. Installed canned 87 tune on 2003 Tahoe with good results. Also just changed tires and used it to change tire size. Notice good throttle response and good shift points. Haven't tried 91 tune or modified yet. I like it, plug and play is nice, it is really just a flash tuner but very nice.
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.
