Calling all Audi Gurus, please help problem solve

Alright so I've had this problem for quite some time now, I think it happened around the time I went stgIII.

My car feels like I have a light weight flywheel or something. It "chatters" when I push on the gas from a dead stop until I get up to around 1500rpms. It is really bad in the morning when the car is cold, when I push on the gas the rpms will drop to around 400-500 rpms almost killing my car then shoot up to 1000 and smooth out. Also another symptom is when I'm cruising in first or second in traffic, if I try letting off the gas, then get back on it as slowly and smoothly as possible it jerks forward. Lastly, not sure if this is related but I would think so since it feels like this has to do with my acceleration from a dead stop but when I try to blip the throttle, it almost seems like my engine is being flooded with gas or something and has terrible throttle response. I was trying to get used to all this but I'm just really tired of not being able to drive smoothly in traffic conditions.

-I thought at first it was a leak of some type, pressure checked - no leaks
-Thought it was my throttle body - removed and cleaned it, realigned it - not better.
-Just for good measure I also replaced all four coilpacks

My cars obviously GTRS powered like my sig says but I'm running Delphi 440's and thought maybe those are my problem but I dont know... I'm too the point now where I'm about to drop my tranny again and just rip the flywheel out and buy a new one (stock one was resurfaced when I got the OFE SS).

So thats basically the run down, any and all suggestions would be great!!! Please someone make my life better, THANK YOU!

Oh yeah, I was thinking of cleaning my injectors or cleaning my entire fuel system. Think that could be it? By the way, I already replaced the fuel filter 5k miles ago too

How many miles are on your clutch?

Did SB resurface your OEM flywheel? Was it inspected? Was everything reinstalled properly, with a new throw-out bearing and pilot bearing?

My clutch only has about 2500 miles on it, I broke it in for 700 miles. A local shop, (same machine shop Futrell's old washington shop used) resurfaced my flywheel to their specs. Everything should have been installed correctly as I am the one who installed it and yes it received a new throw out and pilot bearing.

My only thinking of it not being clutch related is this happened soon after my turbo swap and I just did my clutch a few months ago and the problem has still continued.

Old Guy PM'ed me some thoughts of his and he made some good points like always so I'm going to check that out.

Thanks Dougy and thanks Old Guy!

I just reread your original post. Now I'm not sure if its clutch related. Have you checked all your vacuum lines? Are they all intact or are there cracks anywhere?

I've gone over everything multiple times and pressure tested my car probably 4 times in the last 6 months and no leaks... every time I check for leaks I pray I have one somewhere but nothing. Thanks Dougy!
