I have been running 33" tires instead of the stock 31" for the past year, and the shifting of the transmission was just not right in terms of shift points. I knew that with my plans to switch to 35" tires in the very near future would further amplify the issues with the shifting as well as traction control. So I bought this device to bring everything back within spec. It really did work well. I look forward to using it again next week when the 35's are mounted.

this is the real deal.if you are skeptical don't be. then again if you don't like more horse power and torque this may not be for you.Plus you leave it plugged in for track times and data enquiries.totally change the way my Mustang automatic shifts,so much authority.all joking aside could not be any happier with this programmer!
