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.

2012 JK WRANGLER

Reviewed By David B (Tipp City, OH) Reviewed for a 2012 Jeep Wrangler —3/9/2015 8:49 PM

Software did not seem to load properly...after contacting SCT, found that the instructions to update the firmware were wrong. Loaded fine after a long online update. JK runs fine on 87 octane program, a noticeable improvement in midrange power...some on the top end. Too early to tell if any fuel mileage improvement.
