Jeep MPG eithernwith superchips or stock are so bad, in my case superchips did not make any diference either.
Dependingo on your jeep year and engine fuel injector upgrade has been much better for me, have ask superchips for calibration with injectors upgrade but no answer so far.
I purchased Superchips for the Jeep, and set it for 87 tune. I have seen little to no increase in the MPG. Everything on the SUV is stock. Any suggestions?
