Well I ended up getting a venair TB to IC hose and installed it tonight. When I took the stocker one off I noticed the TB side had a part that was folded in. I'm pretty sure when the dealer did the warrany for the screeching sound last year they didn't put it on correctly when they replaced it. Them damn rubber washer things. Dumbest idea going, fail! Fol. It eventually popped out while it was sitting there. I'm guessing that is why I was getting the noise recently. We will soon find out. If that isn't the reason then I'll do a boost leak test. But I'm pretty sure that was the problem. It really started happening when I went stage 2 with more boost which took it to the next step and started leaking. That's why it's tough to take my car back to the "stealer". At least when I do it I know what and how something was done and have better piece of mind.
The bump on the right bottom was folded or pinched up leaving a little gap on the TB.
