If the cat is plugged up - not all that common AFAIK - a gap you can fit a finger in should do.

may want to prove your intake is not clogged. just b/c you can see in the intake does not mean it isn't clogged in one of the individual ports.

I think that’s the next plan if the cat seems ok. It’s supposed to be nice on Saturday. Do I need any gaskets or anything when I put it back on or are they reusable at all?

One nice thing about the VCDS 'cable' is that you can put it in actuator test mode and it will put vacuum down there to move the actuator, which allows you to see if is actually moving when the ECU asks it to move.
You can also log while driving to see actual vs requested boost.
Also with VCDS you will be able to check the timing. A critical component to all this. And a requirement when you change your timing belt.
VCDS is money well spent.

I got the turbo sorted out Monday night it’s working good now. It just kinda cranks a while before it starts. I ordered the cables tonight. Is there and recommended settings when looking at certain parameters or are you on your own?

Many of the specs, ranges are right in the software. More can be found here- A4 TDI engine measuring blocks/groups (from the OBDII forum).
There is an instruction manual for sale at Ross Tech, but most of us just pick up a little bits of knowledge as we go along.

This probably doesn't have to do with turbo. Extra cranking usually has to do with fuel, or timing. But with that said, I have a couple extra cranks going on right now, and my fuel pump is dry as a bone and my timing is just a few clicks above middle in the VCDS graph, so I don't know what it is yet. Might be fuel injectors. I have a set waiting for it to be warmer than 5 degrees to go in.
Lots of stuff on this forum about using VCDS. Lots of stuff on the Ross-Tech site as well. Pick a single thing about your car, look it up online and try it out. Always make sure you record your initial settings before changing anything.
And finally, search using the Googles. Just type your topic followed by site:forums.tdiclub.com Works better for me than the forum search.

Yes, none of the forums I use have good search engines. A fellow member was kind enough to put this thing together, it's what I use to start- VW TDI Search Engine

Great tips thanks guys! Sounds like I should look at fuel and timing first off. How much stuff do or should people mess with?

I have used VCDS on my 2003 wagon to:
Set IP quantity
Look at injector balance
Check timing
Troubleshoot interior electrical faults
Set new key fobs
Change how my locks and associated horn beeps work
Test my vnt actuator
Log turbo actual and requested
And other stuff I am forgetting.

My car only came with one key. Can I program my own key with this if I find someone to cut it?

Yes. I have a couple blanks and found a local entrepreneur to cut one pretty cheaply.

If you want a new remote you can do it with aarodriguez, aka tunemyeuro. They did a new key using a photo I sent them. Works great.
