Hypertech Max Energy E-CON Reviews


Autoanything great /Hypertech not so great .

Reviewed By Rich C (CHANNAHON, IL) Reviewed for a 2004 Hummer H2 —4/3/2012 6:15 AM

Upon plugging in my Hypertech #33500 and finding it dead I called Hypertech. The tech said to check the cars fuses and I did. There is 11DCV at the plug. He also said that if it had worked I would have had to download the correct program.I guess it would be too much for $309. to expect it ready for my vehicle. So with the shortness of the tech and no real concern for my problem I decided to return it for a full refund. Autoanything was very understanding and set up the return without any red tape. I would not hesitate to purchase there again . There sales person was understanding and helpful.

Hypertech E-CON on Hummer H2

Reviewed By Kristopher L (lumberton, TX) Reviewed for a 2007 Hummer H2 —7/14/2011 10:54 AM

Easy to install. Took about 5 minutes to install. Makes the vehicle run a lot smoother but not much improvement on the MPG's.
