Is there a raised lip on both the turbo and the pipe? Does the hose come off the turbo or off of the pipe? Make sure the clamp is behind the lip and tight so it won't slide over the lip on both ends. How much boost are you running? With a 3" pipe and 25 psi boost the force trying to push the hose off the pipe and the turbo is 175 lbs, so when you test it pretend you are doing a chinup, don't just give it a little tug. I have heard of using hairspray, and some say it works. Dawn would be a lubricant to help get a tight hose on, but it will also help it slide back off so don't use any. Best is to use soap and water to clean the hose and metal so there is no grease or anything else on them, then put them together dry or with a little water if you need some lube. The t bolt or permatorque clamps are best, but the positioning is more important.
