I used to get 9ish lbs of boost.

My internal wastegate actuator rod broke off and ever since, I have been using tie wraps to hold the flapper closed to the wastegate, but it would melt off every couple of days

One day last week I was booting it pretty hard on the highway at 9lbs then it dropped and would only go to 5lbs. My assumption was the tie wrap heated up and stretched letting some boost out. At the same time, I noticed my exhaust got a little bit louder.

Ever since that, when I tried to tie wrap, I would only get 5lbs, for one boot and it would melt (as oppose to most other times, it usually doesn't melt so soon)

Couple days ago I finally fixed my waste actuator, but there is like half a centimeter of play on the flapper (I doubt it would change much)

Anyways now I only getlike 4 or 5lbs(and its like a leaky 5lbs) at 6000ish rpm. The boost doesn't even start to kick in until about 3000rpm. And my exhaust got a shitload louder.

Now what I want to know is, do you guys think that me not getting boost and my exhaust getting louder have anything to do with eachother? Like, what could it be? I know im not leaking boost from any intercooler pipes...so I don't know what it could be.

Yeah my guess would be that something along the exhaust system or wastegate is stuck open, making it sound louder. Hm, I'm not sure. Maybe you could get a friend to gas it a little bit as you listen under the hood...not sure, or you could just use your hand and mess with the throttle.

adjust the internal wg rod?

wg might be venting into the atmosphere.

so you guys are saying my flapper isnt holding tigh enough to the wastegate? i just re tightened all my intercooler pipes, and right now my car is on jack stands, gonna crawl under and see if theres a leak anywhere from underneath. other than that, im fresh out of ideas

it wouldnt be the charge pipes if the exhaust is louder. i think its def the wastegate. open dump sounds sick though lol.

Boost leak!

Check all of your charge pipes, manifold, intercooler, BOV etc...
