Well, last night I did a little highway dash from 60-90 or so. And BOY was it slow. It felt like it was taking forever, I could barely even hear my turbo, and I according to my aftermarket boost gauge, it was only hitting about 0.25 kg/cm, which I'm estimating to around 3-4 pounds of boost, max. I suspected that I might have a vacuum leak before, but I'm not exactly sure how to diagnose that without going to a shop. I do know that I have an exhaust leak, but I don't know where. Is there anything else that could be causing my car to be slower than a sick dog?

Does it idle fine, and seem to run alright? Have you always only got around 3-4 psi of boost cause thats not even factory, also when is the last time you did a tuneup?

it runs perfectly fine actually. Last time i did a tuneup was never, but it wasn't this slow before. :p

Perhaps I blew a hose? S5 Turbo II btw.

I think the obvious answer should be check the intercooler hoses for leaks and the turbo for freeplay, oil leaks, etc (general turbo health check).

Yah, check for boost leaks. Check all your hoses, make sure there arent any just dangling around not connected to anything. Also do a tuneup on it NOW.
