not with a 3.0/10% overdrive combo, that's fairly aggressive.. I'm 3.1 with oem size ATI damper making 13lbs
At what RPM, and what kind of intercooler may I ask?
If you make 13 psi with a 3.1 pulley / stock size crank and the OP made 13 psi with a 3.0 pulley / 10% OD crank pulley, then the OP may have belt slip. He may be able to go with a larger pulley without losing boost by reducing belt slip.
