Jaydee is N.London Essex dont know his add details or number to hand. Maybe someone can post/make them available to you.

Probably the turbo switchover flap sticking open in the union so the second turbo is just dumping all its boost straight out the exhaust. It\'s almost certainly a rat\'s nest problem either split vacc lines or burnt solenoids, either of which will send you insane trying to diagnose. As above, take it to someone who can diagnose it properly :Thumbs-up

If you are still on the standard ecu its very likely boost creep and you ecu retarding the timing, i had the same problem till i switched to a pfc. If your already on a pfc then ill go with a check valve probably the one under the pressure tank.

[lotuscorsa]

spent another 2 hours on it today still nothing:mad:

Do you have an apexi ecu/commander or standard ecu?
Have you tried maybe gettinf a hold of a rats nest diagram and checking for split pipes or one that may have popped off.

[Bobbit]

If you have checked all the one way pills and all the visable pipes for splits then chances are it\'s a solenoid issue, which means taking off the phlenum. If you are confident dong this here is a how to on checking the solenoids: clicky
If you are not confident then take it to a specialist bud

well today i did The Poor Mans Non-Sequential Setup  and now the car  only boost to 0.5 bar ,so before the first turbo was boosting 1.0 bar and the second was boosting 0.5 ,so still cant sort it out:reallymad

[neil_jdmr]

Switching to non-sequential does not fix boost problems contrary to popular belief for starters, you need to check the remaining solenoids are working as they should.
 
Also is your car standard?, do you have a pfc?, do you still have the cat?

[lotuscorsa]

standardish still got the cat and now i have broken a solenoid great

[lotuscorsa]

its got the better of me i have started to do a single turbo conversion:guinness

[HaywardRotary]

Non sequential can fix certain boost issues.
You need to take it to a specialist really,it might not be much wrong with it, the thing is over the net diagnostics are pretty hard.
Kind Regards
