Hypertech Max Energy, pricey,
Hi All, I bought the Hypertech Programmer for my wife's 2010 QX56 and the product listed this model (as did Hypertech's website). BUT they didn't cover this model until about a week after I registered it, HMMM. I guess we'll see what kind of junk mail I get now. Now with the unit loaded, it did install easily and there does seem to be different though we haven't seen any mileage claims yet. The diagnostics feature is nice as you can check and clear codes without going to the dealer. If the dyno reveals power gains and the gas mileage goes up then it is a worthwhile upgrade. I will need to take it to the dyno!
