The upgraded tune does provide for slightly better responsiveness in my 08 Escalade. It also was very handy to adjust the speedo for the plus size tires I have on the vehicle. The Mfg. was also very smart in that they put a warning label on the screen telling you that if the product doesn't light up when you plug it in to check a specific fuse. This happened to me and it saved me hours of diagnosis time. The interface is a little cryptic but it works for it's purpose.
