you don't need o2 spacer or de-fouler at either of the sensors as your tuned
if you can with your oft log AFR (front 02 sensor), Commanded AFR (what ecu is asking for) and Wideband AFR (rear 02 sensor) also log rpm,ltft,engine load. do a couple of steady say 20% throttle runs up to say 4000rpm and post dup logs
those guys at shop should have used NEW gaskets and cleaned up the threads on the header for o2 fittings, they definitely should not have forced 02 sensors into bungs on header.
If they used old gaskets it will leak for sure and if the 02 sensor not screwed in all the way then it wont be in exhaust flow and it will leak causing all sorts of issues.

I just called them. And I asked if they can look at it and install my new gaskets. They won't be able to look at my car until Thursday. Meaning, no peace of mind.
Should I take it to a different shop or wait it out. Thursday is just pushing it since if the problem is not fixed then, I won't have a car for the weekend when I need it.
