Also, another reason for not going for massive boost on the 6258, is I just calculated the CFM, compressor flow and pressure ratio, and at 22 PSI, the flow will be 41.72lb/min at a pressure ratio of 2.496 @7,500RPM; on the map, this puts it at 56% efficiency. Seems like the sweet spot for the turbo is 15PSI
