Simple as that. You're looking at well over a 100WHP gain to go from a 13.9 (stock) to a mid 12, it just doesn't happen.
I actually find it hard to believe anyone with an Evo X is running 12.4, period. They have less power to the wheels than the 9 model did, and they weigh more and have more electronic crap on them. You'd need a hell of a lot of mods to bump the engine up to the kind of power level necessary to run that kind of time.
