Hypertech Max Energy Programmer Reviews


Over a 1 MPG increase AND on 87 octane!

Reviewed By Sean J (Belle Chasse, LA) Reviewed for a 2005 Cadillac Escalade —9/2/2013 8:14 AM

I was a bit skeptical of this tuner, since a lot of them have huge promises, but I got a great price on it through AutoAnything and bought it. I have an Escalade with a 6.0 V-8 and RWD that usually gets 17.4 MPG on the highway at best on our road trips. I got as high as 18.9 and even through a 3,800 miles road trip driving on the highway, city traffic and up hills and mountains, it still averaged 17.3! The cost savings of using 87 octane plus getting better fuel economy were well worth it!

Surprised at the ease of use.

Reviewed By Ken U (HUNTINGTON BEACH, CA) Reviewed for a 2015 Ford F-150 —2/10/2016 8:52 AM

Unit is pretty straight forward and works well. Had to play with the tire size twice before getting speedometer to read correctly. Note my tires from Manufacture said 34.6" and my final input into unit was 34.00" and the speedo is all good. Just remember to reset your vehicle back to stock if taking it to the auto shop if they're gonna plug into the OBD because if you don't it'll erase your settings and your hyper unit will no longer be operable for your vehicle..
