Default Boost control & Internal wastegate (Greddy)


So I've set my link ecu for a 200kpa (1bar) boost target and my wastegate base is 145kpa (6.2psi)

I've tried with little luck to tighten the rod leading to the wastegate actuator, but there doesn't seem to be much adjustment without damaging the rod/can.

I'm running a Denso Subaru WRX 3 port EBC and my plan is to swap out the 6psi can for a 10 psi can to aid spool. Any ideas where I can source said can or is there any other method to increase boost from the stock can.

While I have your attention - what spark plug gap are you guys running for boost in excess of 14psi. I'm gapped to .025" which seems insufficient for the level of boost.
