i ended up "adjusting the pump" ... by hitting it with a hammer. seriously though, i forget the metric, but with the engine running and the VGT cable plugged in as i watched a specific value. my issue was it idled like crap. loosened the bolts on the top of the pump, not so much it leaks, smacked it with a hammer a few times til the value landed in range, and instantly the idle was perfect. tightened the bolts and game on, weirdest thing ever.
