Exhaust Leak?
Well, I my car has been driving a little funny lately, and seems to be getting worse. Well, when I am cruising, its fine. But when I get into boost, its sounds weird and not as powerful as before. My turbo hits boost probably about 4k-4.5k (its a 60trim) and it hits fine at first, but when it reaches like 5k to whenever I shift, it seems to like sputter, seems kinda clogged, and doesnt gooooo.
Well, one day after class, I drove home and I tried boosting it, and I could hear a grumble type noise where the turbo is. I got home, popped my hood, and noticed that one of the bolts that connects the downpipe to the turbo was extremely loose, so i tightened it down. It helped out a little, but still have the same problem. So the next day, I TRIED to tighten down all 3 bolts, but couldnt get to one. What a pain in the butt. But I at least tied down 2 out of 3, which I would imagine still cause exhaust leak. But could that much of a leak cause that much power LOSS?
Or do you guys have any other ideas of what it can possibly be? Besides exhaust leak?

I have an N/A right now so I dont know how helpful I can be, wait for the moderators to chime in, just know that constantly bumping your own thread will not get you answers any faster. I really dont think your symptoms are caused by an exhaust leak, you wouldn't loose noticeable power (I think). I think you might have a boost leak, get in there and tighten all of the bolts and see if that makes a difference. I cant remember when the secondaries come on, but a bad fuel air mixture/lack of fuel could also bog your car down, which would explain why it only happens at higher RPMs. I am just trying to help, but dont know how accurate this information is.

Hey man, I appreciate the help. I got back under my car and above, lol! and tightened down all the bolts I can get too on the exhaust side. It definitely runs a little better, but now I am leaning more on a boost/ vaccum leak. Thanks man... So I am gonna do that today and see if that helps out any. If not, then I will move to the injectors...
