I was disappointed with my 13 avalanche.. It had used 2 QTS of oil in 9000.miles.Was going to trade it for Toyota.I had read about this on net about AFM causing this b.s.GM made a mistake with this.The range kept me from getting rid of my Chevy.so far so good no more oil loss and it runs better than new.1 mile less per gal.and shifts smoother than ever and trans is running cooler than before and have smooth power all the time hope the range last a long time.Thank you Range technologies. Paul

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.
