hi guys im having a mare with this new actuator ,, ive turned mbc right out so should be no boost and ajusted act . ive got it so if i move act arn in one turn ive got massive boost about 20+psi but if i move it out a turn i get lots of turbo lag then bang up to 20 psi cant seem to get it below that ,,,,,,, any ideas before the shot gun comes out ,,,, cheers

Sounds like you've either got a split diaphragm in the actuator or you've got a vac leak from one of the vac pipes which is preventing the actuator from doing its job properly. Have you got any means of applying vac or pressure to the actuator for about 5 mins with the engine off to see if the actuator holds pressure or vac?

Is it the right one then? I trust all the vac pipes are the right way round?

i cant even push the rod in by hand so i think the pressure is fine ,lol

You shouldn't be able to push the rod in when the actuator is unused as it should be fully retracted...

How does it boost without the mbc fitted and just the cars own solenoid plumbed in?

The solenoid only goes in it's holder 1 way.
So he should be able to see the top feed and the bottom feed.

Ok took out mbc and running it just on standard controller with rica I think it should boost at about 12to 14 psi ,,,, am I right ??? If so I'll adjust actuator to that then put mbc back on lol

Sorry to hear that mate.
Ive got a complete block and auto box with 126,000 on it that im about to scrap from the Mrs 850, valve seals gone but you could put the head off your's on if you want to come and drop it out you can have the lot for £75. Was a great runner 14.6 on the 1/4 :)

Ouch! That's not good, hope you can get it sorted soon. While your repairing it, easy to say now I know but, might be worth checking there are no holes or leaks in the vac lines to the actuator and as Merc said get the actuator checked out especially of it went pop with just the BCS fitted as the ECU should have some form of overboost protection to prevent the boost pressures exceeding an upper limit that is unless the HLM maps don't have an upper boost limit protection?

Hi Andy, I was told my "Hlm Map" didnt have over boost Protection, Nor Speed limiter, and rev limit increase.
