Thanks for the replies. The actuator was changed years ago when the Bayjoo chip went in but never saw many miles.
It's not the standard spec one 31/34, never mind which is which but the uprated one.
It's the original standard turbo, done 64K miles.
Should have asked Simon at the time but was so pleased with the first two graphs, never noticed this.
Not actually tried it on high boost and a bit wary of trying 19PSI in spite of Simon saying everything was Healthy.
Used to be set for 8&16 with no problems but I'd just set by the half a hole method when I put it all back together.
Not sure if it's the cam (Piper 285T) or the lightened flywheel but seems way quicker now than I can remember
from 20 odd years ago before these went in.
