Squeak went away after driving a little but there's this weird popping sound but it seems only at partial throttle. I'll see if I can take a vid and post it

well i definitely found out i didnt tighten my downpipe to my cat all the way so im sure thats a lot of the problem/sound and i hope that fixes it when i tighten it. I did it from 12-5am last night. hahaha.

So it turns out the dp didn't mate with the cat correctly even though it was tightened. I think the dp flange is angled a little bit too much. I'll start it tomorrow to see if it is still making weird sounds but hopefully getting a new gasket and putting exhaust sealer on it did the trick

could have possibly been the not so good seal between the cat giving you a little poping or backfire sound. sounds like theres just some little details here and there.

how is the car running otherwise?

It seems to run pretty good while boosting and everything but everytime I let out the clutch it will die but when I started it it idled fine. Also theres still that popping noise im going to upload a video soon. Its kinda quiet in the video but its load in the car and it almost feels like a hesitation. Only at partial throttle too

That might not be good enough. Ill try to get a better one when i get back home

yeah its really hard to hear and determine what or where it might be coming from, what are your spark plugs gapped at?

Oh shit I just actually thought about it but when I put the turbo in my recirc hose wasn't long enough so I just plugged the hose and left the stock bov open. Would that make it run rich when I press out the clutch and also make it drive weird at partial throttle because it's particle open and the ecu thinks it's getting that air when it's not?

yes if you arent recirculating the bov, it will be rich between shifts and there will be unmetered air going into your engine causing a rich state.
