I already have Bassani mids and full Bassani exhaust on the car now. I'm about to put a KB 2.4 on the car and am trying to figure out what pullies to take with me to get he car tuned. I can't base the boost drop off of my eaton because the damn boost gauge is everywhere. I think I have belt slip. So anyway, The KB has a 3 1/4 pulley on it now which is rated for 17.5 I'm wondering if I should also take a 3" and possibly a 2.95 for a race tune? Thanks in advance
