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!

Wow. What a great improvement. I would recommend this to all Ford 6.0 Diesel owners. Driving at 70mph, I get 22mpg!!! Power is there when you need it. I can burn the tires anytime. Great product!

It works like it should

Reviewed By Brandon B (GUTHRIE, OK) Reviewed for a 1999 Chevy Tahoe —11/29/2014 8:00 AM

It's works as advertised. Kind of expensive for what it does but , it's cheaper than having a shop do it wrong.
