This should be the first "mod" you buy for you car. Easy install and needed for those power gains!!!

Must have if you care about your WRX

I am completely happy with how the WRX is driving now. With just the OTS map you can tell the difference. It gets rid of all the nuances, the best part is pro tuning capabilities. That way you get what you need for your vehicle!
