Hypertech Max Energy Programmer Reviews


Exactly what I wanted

Reviewed By Ned R (Granbury, TX) Reviewed for a 2007 Chevy Avalanche —2/20/2015 9:23 AM

My 07 Avalanche is used for most of our travel as well as pulling our 21' travel trailer. I was very disappointed in the Avalanche power above 50 mph. The programmer has allowed me to pull the trailer about 10 mph faster and has increased my fuel mileage by 1 mpg. I did also add a K&N air intake. Now pulling the trailer is pretty easy. I also get improved mileage around town.

does the job

Reviewed By lawrence c (LENOIR, NC) Reviewed for a 2013 Dodge Ram —2/27/2015 2:03 AM

This item does what it says it will. Is a lil expensive but alot cheaper than a speeding ticket. Wish it would allow changes in tenths of an inch instead of quarters.

hyperpac pays for itself

Reviewed By Jason F (PALMETTO, GA) Reviewed for a 2005 Dodge Ram —3/20/2014 10:39 PM

Extremely ez to install. Just get in, close all doors, turn off all accessories, and follow. Performance went up est 15hp at least. Mpg average up 1.5 mpg. Up 3mpg hwy observed. Very useful, monitor actual water temp, trans temp and much more. Practical can potentially save a lot of money! Just be mindful that the gas pedal is more fun. Id buy again.
