Not 100% sure but that sounds about right.
Someone will jump in and school my *** I'm sure, but stock pulley is ~12-13 psi
178's and code3's are ~15-16
181's are ~17-18
and the elusive 185 (or stacked 178 and c3) are ~18-20

ECU throws at code at 18 psi, and our stock intake mani gaskets don't seal well past 10 anyways.

Hope I got that right...so if I DID get it right....we now have boost readers that don't look out of place!
