ok I get ya that sucks cause one of the updates, fixes the mds surge, you could try it cause you can always go back to your origianal tune if you dont like it, thats the best part of these tuners you can always go back, the other thing you could do is send Diablo your current tune and they will put the surge mod in your current tune, I am surprised they didn't offer that to you. I like Diablo those guys are very helpful IMO.
