thanks for all the advice you guys are legends

yeah gone 3 inch dump pipe back

solved the problem. it was a blocked up catalytic converter causing back pressure which was causing the turbo to sound like it was boosting up

its out of rego right now until i can get it fixed so dont really want to go driving it to find out

could it be a blocked catalytic converter doing this?

yeah that reading is in the driveway. dont think the nps is playing up as the revs are dropping when going through the gears with it on

a quick thought a couple people have mentioned the wastegate being stuck open or closed now i did swap the actuator out and with the rod coming out of the actuator disconnected it moves freely but with the rod connected i havent got a hope in hell of moving it. does this sound right/normal

i did swap it out for a second hand map and i replace all hoses to it cause thats where i put the t joint for the boost gauge

Yeah will do

Yeah doesn't seem to have power and I can hear it spool up as soon as I'm on the throttle where as before you wouldn't hear the whistle until 2500rpm

When I changed the actuator over the waste get was opening as closing freely. The map sensor and boost are the same thing aren't they? If so I changed it but only with a second hand one I will hook up a boost gauge tomorrow and confirm the psi
