Stage 3 cossie only boosting about 10psi?
Apologies for posting this in the general discussion but i did post in the Technical one but didn't get many responses.
Here's the problem, my car only seems to want to boost to around 10-12psi, i have changed the actuator, amal valve, hoses, and intercooler since this happened but i still can't figure it out, any suggestion welcome. Other that that the car is running as good as gold, no misfiring, it basically drives like a standard car, which is not what i want.
Thanks in advance, Rog.

Ok cheers dude, so r u having the whole car then, another one to add to the collection??? 
Definately not going near any bleed valves i hate them with a passion! I've ordered a garrett -31 actuator, should get it tomorrow but i don't think that's the problem. i've had the turbo off and checked the wstegate, there's nothing odd looking there either. Cheers for your input guys

Cheers, i've tried all that, removed the dump valve etc..... got a new actuator, checked the amal valve, changed the hoses and intercooler, but still no more boost, i just cannot find ANYTHING wrong! yet the car runs as tho it's standard, pulls well for the boost it's running.

Beliveve it or not i've actually tried that....... 
It's the 3rd on i've tried so it can't be that, it was boosting about 20 odd psi for about 2 years and then one day it decides to go to about 10 without me touching anything.

try connecting the hose direct from the turbo to the actuator
and see if the boost changes atall
if it drops lower then adjust the actuator up and see if the boost will now go above 12 psi

20K+ Super Poster.
you could take the hose off the actuator (so the wastegate wont open) n see what it boosts to... if it shoots off the boost gauge n goes like stonk then the wastegate/turbo's probably ok n its just setup wrong... if it still boosts to about 10-15psi then you have a problem with your turbo and/or wastegate

do like i did yesterday;
Take off hose at actuator, then it will run full (as actuator is adjusted). when full boost is adjusted put hose back on actuator for ECU controll of boost.

I've got a new amal valve and -31 and i pressure tested them both with a pump, think it may be the turbo just struggling now. I cranked up the boost today and it only hits 19psi peak, i was giving it some on the way to work 2day and it cut out when i was in 4th about 5k rpm, pulled into the side and it statred again first time so it seems like something electrical could be causing it? Give me strength!
