Back in 2011 when I had an 11 Sti, the dyno tuners, pro tuners I used literally laughed when anyone asked about running off the shelf Cobb files, I sent that particular tuner allot of business I'm sure because after smoking other similarly modded sti's that were running Cobb of the shelf tunes, always asked what tune I was running and inevitably the next time I saw them they had dumped the Cobb tune.
Personally, I think Cobb and dumb kids are responsible for the majority of ring land issues. There are way better options out there, even those stupid signal modifiers are better than Cobb on any platform in my experience and opinion. Seriously spend somewhere, anywhere else!
