Hello 86ministock, I'm glad my suggestions helped your idle situation. What track [and how long is it] will you be racing on? I don't know what the rules are for your class, but I'll bet they'd allow you to remove the whole A/C system. I'd get rid of any unnecessary weight. Also, if you'd like a bunch of low buck performance enhancing tips for a B11, go to:
