I just blew that boot off on Sunday with my boost psi between 30-32psi (I was using Innovatives tow tune)towing our 5er up a long steep grade. I had to improvise on RoyBoy's advice and use my wifes Strydex acne pads (it's was all I had at the time) and put some hair spray on the boot before I put it back on and tightened up the new clamp. I am going to spend the money shortly on BD's improved boot and clamp kit so the next time it's not one of the lower intercooler boots that go. I don't even want to think about what kind of PITA it would be changing a lower boot would be on the road.
Well that's what happened to me in January. I was lucky that it was sunny and dry but still it was enought to convinc me to go buy new "upgraded" boots for the intercooler connections...I'd done the easy ones already of course!!!
