@vinnytitty "The reason for this is the EPA mandated greater restrictions on ECUs for 2004+ and allow manufacturers to exclude one model. Subaru chose the STI as the exclusion, so the restrictions are not on the STI. The restrictions have to do with the open and closed loop fueling. To put the restrictions in a nutshell without being technical, there is a delay between open and closed loop fueling that can allow your 04+ Subaru to run lean during this crossover point in how your car gets fuel."
@unknownally "Lean is dangerous as it produces detonation which is the #1 factor is blown pistons. In stock configuration, 04+ turbo models are fine, but modifications such as exhaust work or higher really necessitate the use of engine management as those mods cause the fueling issue to rear it's head."
"Yes, you can run certain mods for a short time until you get engine management, but you should never kid yourself on 04+ turbo models that bolt on modifications are fine without engine management."
I doubt theres tons of other shit, because you need to tune it for almost every single mod, unless it's something like a clutch or shortshifter.

@vinnytitty Then that isn't a Cobb Stage 2 tune, it's a protune, done by a professional tuner.
