This thing unleashed the beast

Reviewed By Dan D (PLAINVILLE, CT) Reviewed for a 2009 Jeep Grand Cherokee —7/25/2016 8:18 PM

Huge difference in my 4.7 Grand cherokee...woke it up! this thing runs and gained 2 mpg in fuel economy. Only reason I rated ease of installation low was because I haD TO WASTE 15 mins updating it on my pc. for the amount of money I paid it should be pre updated. and its a bit pricey.

2007 Jeep Wk Lifted

Reviewed By Eddie C (NEWPORT, NC) Reviewed for a 2007 Jeep Grand Cherokee —3/20/2015 8:16 PM

Does the job as advertised. Recently lifted my jeep and put 31" tires on. Prior to installing the calibrator, the speedometer was off 7 mph. When reading 55 on speedometer, GPS showed me going 62. After calibrator installed, speedometer is dead on with GPS speed tracking. Would definitely recommend and may upgrade to the max energy software.
