I am selling a Blitz Throttle Controller For a 2008 Sti. It is still just like new; I've only used it for about two weeks. It gives 4 levels of response to choose from. Eco, SP1, SP2, SP3. Throttle response increases noticeably with each level you select. Installation only takes about 7-10 minutes. I am away from home right now so I don't have a pic in my car, but I found a picture of one in a wrx.
I paid $350 new, and I am asking $280.
