Why so much hate on impellor? Clearly hes not just spinning this sh*t from no where. He's putting in the effort and researching all this sh*t in order to improve OUR cars. I believe him when he says no bov is faster. It makes sence.
Give Simon a call and mention your off the forum. I'm getting my next round of mods done by him. Pm rip hsv or blkphn and ask them about there experiences with tuners.
