Thanks! My idle is set to ~950 RPM, so 3.2 g/s is probably close to where I should be. It did idle fine for some periods.

Just ACE with Delicious tune. Stock everything else. I have no concerns about the tune. The car ran pretty much OEM-like for the first ~400 miles the kit was installed with the only exception being a little bit of initial idle learning. It also ran fine for ~50 miles after installing the longer coupler. I think it's absolutely an install error on my part or some hardware failure in progress. I'm having to troubleshoot in a parking deck for now so lighting is poor.

When I removed the intake pipe the throttle body looked clean. No oil buildup around the plate etc. The more I think about it, I'm hoping it's just some oversight in putting the intake pipe back on. It is dark under the hood and I didn't check that elbow very well before deciding to grab a datalog out of frustration because I was rushing to get out of town for the holidays.
