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.

I was very skeptical about any real change in power or mileage claims. The recommended setting by Banks was the sport setting. I tried it as my first option and I'm happily surprised with the results. Noticeably more power and mileage right away.
