boost hose failure , grr

Hi guys , i know that im not alone with this issue.
After my initial running in service i turned the traction off and went for a blast only to blow a lower intercooler hose off almost straight away.
After getting the bmw dealership to take a look over and tighten ALL the boost pipes i thought that would be the end of this annoying and some what embarresing issue.
Lets face it. Having to return to the garage due to any relyabilty issue isnt great news when showing off your new toy to your mates lol.
Next dry day and first propper time shes let rip ( again with a friend on board) and sure enough - theres a ton of waste gat noise and a pop from the exhaust and no turbo pressure.
This time i went to my pals workshop and tightened all the hoses includind the top hose which had come lose then informed the dealership of the fault.
They ordered a new hose although i couldnt SEE a noticeble defect in the original and all was fine for a few months of spirited driving.
Until today.. Tc off, slight sideways moment in second coming off an empty roundabout and you guessed it ...POP!
This time i think its the bottom hose as the top ones are all tight.
The car is standard and due to this issue im not able to mod for fear of having to constantly check into the dealership to get it fixed up on the ramp.
Im also waiting on spec r to have time to build me one of their custom inter coolers ( mine will be the first 1M to have one) and will also get a hard pipe kit made at the same.
Has anyone else suffered this repeatedly as im at a loss on how to prevent it.
Its not the same pipe every time so im assuming the whole pipe run is not fit for task???
Cheers jamie
