CB-
I'd go about 1/2 turn at a time, and see how you like the improvement; go a while unless you know you just HAVE to have more. 2 turns is about the max I'd go. But, someone said if you dont use the power, you wont put the pressure on the pump. Now dont go making those ricers and daddy's boys in their new gassers feel too bad
formula-
CB aint legal yet. But, if he takes a couple cases to a sorority house, he'll get all the R&R he can stand. Been there, done that.

Bottle of JD or Crown has similar results.
JLEONARD-
Go for it. You need a new 230 pump from one of the vendors, anyway. Let's see, math class- 230 hp divided by 160 hp= 1. 43. If I'm not mistaken, thats more than a 10-15% increase in fuelling.
Happy BOMBing
