I currently have a 2006 4.7 Jeep Commander and getting ready to buy a lift kit and new wheels to give it a more aggressive Jeep look rather than a mini van and trying to compensate for the mpg with the tuning hoping I get about the same. Anyways I was looking at a couple post on here and ran across that there are a couple different tuners I can choose from. The one I have in mind is the Superchip 3875 Flashpaq. It claims to do everything I want it to with a plus: having tire size calibration and them being around for a while. If anyone is running this tuner what are you thoughts about it? Do you like it? Would you recommend it? Or if you are using any other tuners how do you like those? I want to order it by the end of next week, but no hurry on the purchase since I won't be able to enjoy it quite yet since I'm am deployed. But the wife is going to have everything ready for me for when I go back home. Any and all comments will be beneficial. Thank you.
