"I drive a 2009 Suburban 2500 with the 6.0L motor. I ordered the Max Programmer because I tow a 24 foot enclosed car trailer and the first time I towed with the truck stock it was very sluggish. I looked at other programmers and decided on the Max because the dyno sheets showed good power at and below 2500 rpm. When I got the unit I had to go on Hypertech's website and download an updated version of the engine program. Lucky for me I have a PC laptop because the software is not Mac friendly. The install went well and the truck is more awake, however every now and then there is a little hick-up and there is a little bit of a hesitation. Mileage also has suffered. I drive very "balloon footed" around town and pre program I was getting 13-14 MPG town and 17-18 mpg highway, that has dropped with the program to 10-12 around town and 14-15 highway. I think when I tow and need the extra oomph I'll install the software, but the rest of the time it will be stock." —Thomas N from Rochester, NY bought a Hypertech Max Energy Programmer for a 2009 Chevy Suburban, 6.0L V8.
