"Programmer was nicely packaged and quality felt very nice upon receipt. Upon attempting installation I found out I had to go online and download the program for my vehicle so it does not come pre installed like the other name brand I purchased for my 2001 F250 7.3L, a little irritating but completed and installed with no further delays. Installed in Oct 12, noticed immediately shift points improvement which was my #1 desired goal, possibly a slight increase in fuel economy. Would Recommend!" —Stacey B from Ruther Glen, VA bought a Hypertech Max Energy Programmer for a 1999 Chevy S10 Pickup.
"After the installation I have realized 2 mpg increase and better off the line torque. I can't say I am tearing up the streets or competing with hybrids but it was worth the money day to day." —Scott M from Harrington Park, NJ bought a Hypertech Max Energy Programmer for a 1999 Chevy S10 Pickup.
