Thanks guys
Also has any one done the so called $2 mod with the t piece. If so what diameter vacuum line do I need and what are your thoughts did it make a good improvement.

Congrats on the purchase of BULLITT's SP - you might like to add yourself to the SP owners list:

Can't remember the vacuum hose size - 5mm maybe. Maybe mine went from 130 to 147 rwkw on the dyno with the mod, no real downside. That said mine used to ping terribly under load (before and after mid) so I went with low compression Wiseco pistons when I built the motor.

Thanks big dog will do it this weekend have ordered parts. Great to see you had a Dyno result. That's a good gain for a simple mod and a cheap one at that.
