HyperTech 2012 Suburban 4x4

Reviewed By Arnell S (KEAMS CANYON, AZ) Reviewed for a 2012 Chevy Suburban —4/21/2015 2:45 PM

With the installation of the HyperTech Max Energy Programmer within the last couple of weeks.I can definitely feel the power increase when I step on the gas. I have not yet taken my vehicle on any long trips to see if I get better gas mileage as proposed increase. Install was easy and took 15 minutes. I wish there was refence sheet to upgrade my shift points and rev limiter for even more power gains.
