Thanks for the help.
I do not have a original inter-cooling system, but a water-cooled system, so RarlyL8 you are correct.
Because of my hard 1. gear run the turbo pressure made the silicon hose on the inter-cooler inlet to pop of. I discovered this when i started to dismount the pipes.
It was very strange that the engine will not run at all if it doesn't get air from the the turbo, not even on idle running. So the conclusion is that the engine did get too much fuel and when the fuel amount is way too high the Inovate LC-1 wide band AFR gauge does give a wrong indication, so it looks like there is not enough fuel but in reality the mix is pig rich.
i connected the silicon hose and everything worked fine.
and here you can see why i have a watercooled system
