On the 180hp and stage 1 MPI uses Rotrex c15-60.
Info from Rotrex:

The 180HP kit makes 4-7psi @ sealevel (155-180hp) boost depending on gear ratio of pulleys, if you want to push it some more you need to use race gas and add a intercooler.
Last year i used 28/28 gearing for about 6 psi (sea level) and only use 92 premium, if you are unsure of the quality of your fuel you better go for a lower gearing to have a more fail safe setup.
