Hypertech Max Energy Programmer Reviews


2003 Jeep Rubicon

Reviewed By Timothy K (Victoria, BC) Reviewed for a 2003 Jeep Wrangler —3/11/2008 7:58 PM

I reprogrammed my stock 4.0 litre 2003 Jeep with the Hypertech Max Energy Programmer, the reprogramming was simple, just fllow the instructions. I was able to set the RPM limit 500 rpm's higher, and programmed for horsepwoer/torque on 86 octane fuel. I could feel the immediate different, the lower rpm torque could be noticed, but the biggest improvement was at higher altitude, the power was there, that wasn't before. I was not afraid to pass slower traffic, as before it took considerable distance to pass slower moving vehicles. It also can clear or diagnose most error codes, which is helpful.

2008 Jeep Rubicon 4 door

Reviewed By Phil B (Denton, NE) Reviewed for a 2008 Jeep Wrangler —9/6/2011 5:32 AM

Prior to installing the Hypertech, I was getting 17.6 mpg on the highway. After installing my mileage went up to 21.5 on the highway at 55 mph. The added horsepower was also noticeable at all speeds. Excellent value.
