A cost extensive and striking tune up.

I bougt this unit for my stock Grand Chereokee `94. It is easy to install, I only had to pick out the can for the coolant. The electronic and engine is in a better balance and more straight than before. For this price, this is an unbeatable tune up.

2005 Jeep Grand Cherokee Hypertuner

Seems a little snappier, off the line but as far as huge performance gains, I'm not seeing it . Gas mileage is up approx. 1 to 1.5 mpg so over time it will pay for itself. i originally bought the unit to erase DTC codes after the N23 recall. It erases the DTCs and is very easy to use. Had bought a Superchips programmer but they do not support the 2005 Jeep 4.7 liter motor, Hypertune
