Turbo Vacume question?

I installed a TurboXS boost controller on my MSP. I notice the other day coming home from work that my vacume line going from the wastegate to the B.C. was sucking together and going flat. I'm not sure if that is a normal thing. I was running it a little hard on the highway and it was pretty hot that day around 85-90 degrees. should I purchase stronger hoses or might it be a larger problem I need to look into?

i don't know if it's normal, but as long as it opens back up when it's supposed to and lets the wastegate see boost it should be fine. i'd be worried about it not opening back up and just spend a few dollars and replace it.
 
What kind of hose are you running? Cheap silicone hose will flatten out under vacuum.... get Hosetechniques hose, it's much better.
