Oh man I had forgotten about that one. I had one of those that blow apart on a test drive after an engine swap. I didn't know what happened, but it felt like someone had stolen about 5 cylinders worth of power. Those are a PITA to keep in place. The only way that I could keep it together was to remove the pipe and clean the entire inside of the hoses out with brake cleaner about three times. That was my boss's truck and he had the biggest power chip (yes, old school) that he could find in it. So I'm sure it was putting out more boost than stock.Mystery solved! It was the charge pipe under driverside battery box which made it difficult to see! Some knucklehead didn't tighten the clamp (me). Reconnected the pipe, tightened the clamp and wow what a difference!
