Ive got a pulsar 3576r gen 2 strapped to a na+t that’s currently at 500whp, im fitting new rods to it in a month or so then going back for a re tune, it has a 0.60 front and a 1.06 rear.. mates said I may have issues with the turbo choking at top end? Could this be an issue? I’m thinking fit an external gate to combat it?
