Do you still have the boost sensor fitted?

It's in the pipe that connects the turbo to the intercooler. That will cut the ignition is the boost goes over ~1BAR from what I can remember.
I don't think so are all non standard hoses the dyno tester said it was the ecu,

Hi guys I'm still having trouble with boost I can't get above 14 psi I believe it is the re 209 ecu stopping boost is this possible?iv taken it to a dyno centre and thay say it's the ecu?have a new t25/t28 turbo so should be good for 25+ psi

First, make sure the choke flap is correctly adjusted. When the in car level is down the flap should be fully open.

There are 2 screws to play with. The idle mixture screw and the idle speed screw, it sounds like the idle speed screw wants to be wound in a touch.

If the idle increases but the revs still bob up and down quite a lot then you might need to have the mixture checked.
Cheers mate I found my boost problem pipe was off back of old boost gauge seems to be fine now is going for dyno set up Wednesday  :D

Standard boost gauge is connected to the carb elbow, it is 'T'd into the pipe that wanders off into the top of the fuel pressure regulator.

Aftermarket boost gauges are 'T'd into the vacumn pipe that connects the AEI unit to the inlet manifold (at the rear, base of the carb).
My pipe from aei isn't connected to any thing is a thin hose comes out the black plastic cover and is this the hose that should be into manifold with boost gauge t in it?

Yes. It should connect to the rear of the inlet manifold, a small port at the base of the carb.

If that port is left open then that would be a reasonable sized air leak.
Could u post a pic of where it sposed to be ill see what's on it I'm sure everything is connected up on manifold mate

An actuator needs a certain amount of preload to build boost, it won't build any boost if it hasn't got enough or any preload.
How much did you adjust it up by?  Do you have a standard or after market actuator?
If I put it all the way down and then turn it up 2-3-4 Turns ? it should be making decent boost yeah ?

It has a big ally one I adjusted it a few turns then pulled it and hooked it back that didn't seem to do much so I did nearly till it wouldn't reach and it still didn't seem to do anything

A large turbo like that only running at 7PSI will feel sluggish, when does it spool up 3500RPM+?

Check for leaks first, you don't want to keep winding the actuator in only to find out it's just leaking out anyway.
I wouldn't say it boosts hardly at all I'm sure I don't have a leak iv set the actuator low my rev gauge don't work so can't see rpm in a bit stuck ATM mate
