T28 BOOST PROBLEM
My cossie is running hardly any boost at all.
On standard boost gauge can only get it to just past large segment (not sure what boost that is) and car just feels dead at that point.
I have tried a different actuator which i believed to be standard and boost was less. The one on the car felt stronger which i have now put back on.
I have tried running with pipe from actuator disconnected (briefly) to see if elekron valve was problem and boost was marginally better but still not good.
I have since fitted a GGR chip and car feels a bit better at low revs but still same max boost level.
Any ideas what else it might?
I,m thinking turbo not holding boost but its doesn't smoke use any oil at all. Theres some side to side play on shaft but no in/out movement.
Thanx in advance
