Procharger P1X pulley swap.

[LSchicago]

I ordered my P1X stage 2 kit with a 4.38" pulley for 12# of boost on E85. My tuner wants me to install a 10# pulley for tuning on 93. The question is if I go with a 4.50 pulley to tune with, will I need a different belt than what was supplied for the 4.38" pulley?

Probably not, tensioner should have enough adjustment.

Thanks. I'm thinking of just swapping for the initial tune.
