I have been doing some research and I was wondering which unit is better? We all know about the Diablo Tuner but does anyone on here have SCT tuner? I was talking to a friend of mine who has been into racing for a long time Kit Dickman and he was speaking very highly on the SCT over the Diablo. I need some serious feed back as I might be handing over my Diablo for a SCT tuner. I don't want assumptions but your opinions will be taken under consideration. Just trying to make a wise move and not go back wards. Thanks in advance, Jay
