I have read lots of info about ******* and PPEI with the EZLynk, but can't seem to make up my mind. I currently have a 2011 with GH tunes on SCT X4, EGR Del**te, and Banks Ram Air. The GH tunes aren't bad, but I feel like there is better out there and I really want SOTF. I do a fair amount of city driving so I need something that is for the daily driver. I am not looking for the highest dyno numbers just something that will run good and have a nice trans tune. I wish there was a way to try both of them, but I know that is impossible to I am hoping to here from someone that maybe has tried both.
