I have completely removed the boost solinode which runnes from the actuators to the the vacum pipe. I thought leaving the pipe of the actuator would leave it to constantly bleed of the vacum causing the wastegate not to open? The sensor to the left of the brake master cylinder is that for boost cut?

Thanks that's a great idea, I will try that tomorrow. On closer inspection I noticed the rear turbo has shit loads of oil inside the boost pipe just after the turbo so it could do with a new turbo anyway. So I will probably change the whole set up soon anyway.

Ok i blocked of both vacum lines and still low low boost. I have done a boost leak test and it's holding Pressure. I plugged up a pressure tester to the actuators and they are opening well before 10 psi. So I'm leaning more towards the actuators / waste gates. I'm guessing the only real test now is to pull of the turbos and have an inspection.

I also forgot to mention. The car also smells as if it's running very rich and the car seems to be burning a lot of fuel too, I'm not sure if this would be anything to do with the possible boost leak?

Thanks for the replys. Today I couldn't find anywhere to buy the parts to make a boost leak tester, so I have ordered all things to make one of the internet so fingers crossed I will get them in the next few days. I am running the two vacum Hoses which go to the stock boost solenoid, to the now new boost controller. I have also replaced all the vacuum pipes which run to the turbos with new ones. Thanks for that I will block of both the vacuum pipes and take it for a spin tomorrow and see if that makes any difference.

Thanks for the reply. I'm running an aftermarket gauge, both the stock gauge and after market gauge aren't going up beyond 8 - 10 psi. I haven't pressure tested the system yet. But I thought If I would have a boost leak wouldn't I here a hissing noise? I was thinking about it last night if one of waste gates wasn't sealing would that cause it only to boost up to 8 - 10 psi or would it still boost a lot higher with no vacuum pipes connected?

I have always had a problem with my car not boosting over 10psi the vehicle had already had the restrictor removed so I thought by replacing the factory solenoid with a boost controller it would get rid of the problem. I took the car for a drive and it was still the same so I removed both vacuum pipes from the boost controller to see if the vehicle would run more boost and still the same, I have replaced all the vacuum lines too and no success? Has anyone got any ideas it frustrating the hell out of me haha.
