KaosBanshee44 Posted October 23, 2009 Report Posted October 23, 2009 I wouldn't think you would need anything higher that would be just fine Quote
AKheathen Posted October 23, 2009 Report Posted October 23, 2009 if all you have internal is new pistons, no head mod, then you are better off just running strait 93, or do you guys have pupm 95 there? Quote
