I'm looking at getting a programmer it chip so that I can et little more power outta my jeep. But when it comes to that I really don't know what to get I do know I want one I can change the tire size with so my speedo

 

And my has mileage can be right finally. I'm running 33's so I want something that will help me turn them a bit.

 

I was shopping for the same thing... I went for the Bully Dog GT gas tuner, but the other option was the Super chips Flashpaq... There are others available to.

Went for the B D for 2 reasons... every one in SA goes for unichip or Super chips, and It has the trans temp gauge, that will keep me sane when going into the desert.
