all they have to do is raise the rev limiter a little and there's your "increase" in power. A redesigned air box can result in 10-15 hp more. What i'm getting at is it won't take a lot and don't expect another 75 hp for those that are speculating and getting their hopes up.
I wouldn't expect anything drastic like new redesigned cylinder heads or cam or something lol.
small simple changes .
In the end, who cares, it's not like you're gonna keep your car stock anyway..
