Thanks for your reply. I had that replaced last week, took it out for a drive this weekend and the same thing happened. What I can't undertand is why the elctrics go dead but it then restarts without any problems. Not really sure whether there are any other relays worth considering?
Stock boost is something like .8bar isn't it?
The stock overboost switch opens when it detects more then stock boost. I'm just picking a number out of the air but lets say it trips at 1.1bar. You've increased your boost by virtue of your 1 bar spring so now you are much closer to an overboost condition. Under boost you will experience short periods of boost greater than 1 bar even though your 1 bar spring "limits" boost to 1 bar.

A friend with a '91 911 Turbo when through this and ended up removing the 1 bar spring.
