I had the superchip before the edge and I noticed last night that boost on the SC would max out as I press the go pedal smoothly without downshifting around 2500rpm and up. The edge just isn't maxing out that boost guage. Also the edge the tach sticks to the top end so I really don't think the torque converter is is transfering the power very well. I'm thinking about loading the lowest setting with the superchip for the tranny program and stacking the edge (not max setting) to see if it will run harder. I wish I had some damn patience and went with the Banks from the get go. The superchips tuner is pretty sweet for the price and if I end up being dissapointed with the Banks I think I'm gonna cry.
