I decided on the Superchips programmer and I'm happy with it so far. I got it for $290 to the door brand new. It has 3 settings and can adjust for tire size. I installed it on the lowest setting which is good for about 80hp and 130tq. I need gauges before getting wild, I just couldn't wait to install it's just plug and play and took ten min. It is raining here so I couldn't get a good test but at 60 the power is a lot more then stock. I put it in 4x4 and floored it from a stop light and when the turbo spools it struggles for traction and really launches. It is so wet here in 2wd it just fish tails through all the gears. I'm certain my old Hemi would only win for the first few feet in a race.
