The rpm jumps up and down for a while. It stables after another few minutes but it still feels like it wants to stall slightly here and there

You're DBW, so no IACV to clean - perhaps dirty TB plate? Bad wire/connection to TB plate?

Check all engine grounds; do the GND mod, esp to TB. my 0.02.

I believe the worx is recirculated. I read something about 50/50 vent and recirculated

If you have the stock BPV, you could try throwing that on and see if it makes a difference.

Is your car pro-tuned?

Just depends on the shop.

If you go open-source or Access Port.

Some shops will tune either way, some will only do one or the other.

There are tons of shops in/around SF that do great work.

Ah I see. Do you have one in mind that you would recommend?
