Stock car with Katana and stock pulley. 2bular 8 inch exhaust. 217 rwhp and 140 lbft torque. Shows AFR slightly lean at 13.0 max. Also shows partial pressure falling as revs rise probably indicating 'throttling' of air intake, so next move is a better intake system. Hoping for 220rwhp and 150 lbft without charge cooling. Would like to put a 3.2 inch pulley on just to see what happens but an worried that already running too lean to try this. Opinions always invited
