need a half second

I love my ACC converter....it has been great but you can't go wrong with Dynamic or PTC either but I feel ACC quality is the same as the others they are just cheaper. A converter will make a huge difference. A 650 DP will be perfect as well....a 750 will be to big...I just went thorugh all that. I just bought a Bigs Stage 3 650 DP and it is fantastic....it's like I'm driving a whole new car....tons more low end and the same top end.
