Fixed the remaining vacuum leaks finally. I bought new exhaust gaskets and was all prepared to put them on, though I was worried about snapping a bolt holding the heat exchangers on since I don't have a way to heat them up. Decided to first try torquing the bolts on the flange I saw the leak at, and found out the leaking one had a bolt below torque spec. Tightened it and checked all the others and ran smoke again. All buttoned up!

Drove it around this afternoon and, along with the new spark map I put on, put down a much better tune. Everything is running smoothly, and the car is a ton of fun. It's making it hard to decide what to do as I've begun actively searching for a 964/993 DE setup car again to replace my M3.

One of the reasons I decided to look for vacuum leaks was the misfires and because I could not get a stable AFR. Misfires are much better but the AFR is maybe slightly better. It constantly jitters. I don't know if that's normal, if I have constant misfires, or if has some noise being introduced. Can anyone pass along some knowledge or give some thoughts? I attached a screen cap of a log I took. It's the yellow line on the bottom graph. The table on the bottom right shows how much it changes in the little section I highlighted with grey bars.
