Yeah, it sounds like a minor screamer. Which I had always assumed was just the wastegate opening and the fact it has a bellmouth dump pipe. Happened with the last turbo too ... leak both times? So its either normal, or I got a small exhaust leak. No performance loss, no loss in boost, just noise. I'm aware of the hose-to-ear trick and I'm giving it a go tomorrow. Only does it high rpm/max boost.
Still wouldn't mind just putting mind to rest and ticking that one off the list.
I'm certain he was working on knocking me down in price. Asked me if I could take Stagea to boostworx for a check, then if all okay he'll buy. Nope. Done that before in the past. Potential buyer got me to take it to Hitech and came up with false problems and tried haggling for a free car pretty much Then left me with the bill for the inspection. Never again. As is, or not.
