Hypertech Max Energy Programmer Reviews


Performance plus!

Reviewed By David W (Edneyville, NC) Reviewed for a 2008 Saturn Sky —4/1/2011 2:45 AM

I installed the Max Energy Programer on my 2006 Chevy P/U - I have the "B" motor, the 5.3L HO and had already installed an S&B cold air box, Jegs Mass air flow sensor, performance single exhaust and 4:10 gears. Installation was a breeze and took aboiut 10 minutes.The truck was already a great performer and the improvement was immediate. I had firmed up the transmission shifts 50%, and set it up for regular gas. Acceleration improvement was crisp, over and above from what the truck already was and shifts were firm but not harsh. Fuel economy went from 17 MPG to 18.9 MPG average at freeway speeds of 65 MPH. Truck is now very much on steroids and is a real sleeper!

Hypertech Speedometer Calibrator Reviews


works great

Reviewed By William W (COLUMBUS, OH) Reviewed for a 2014 Chevy Silverado —6/27/2015 12:06 PM

I initially set the unit for 34" tires, the diameter of my Toyo ATIIs in 295 60r20, the speedometer was actually a couple mph over. After some downward-tweaking for tire inflation level, I setting the unit to correct for 32.75 inch tires got my speedometer accurate to within less than 0.5mph error compared to Garmin GPS. Keep in mind that actual tire diameter is dependent on how many psi you are running, so getting things right on the money may take some tweaking.
