Finished my car on sunday night, took it out and the car pretty much ran perfect the first night, and the next day. A little on the rich side according to my af gauge, I don't have a wideband yet. Im running t3/t4 external gate at around 9psi, ford greentops with a 2025 cartech begi fmu and stock fpr. Heres the problem, tuesday night i drive home and the car throws a check engine light. Starts to run excessively rich and nearly chokes itself and dies out close to home. I pull into the garage and at idle its running real rough and missing, bouncing from around a 1000rpms down to around 600. Lots of black smoke coming out of the exhaust. Next day today, put the car on a scanner to check what the code is i think it came up P102 02 sensor high output. So I cleared that and took it down the road and it runs rich again but doesn't choke itself out. Tried unplugging the vacuum line from the stock fpr and capping it off and it seems to like that more. It tries to run towards stoich more, but still runs real rich during cruising and idle. The code re-appeared on my way home and I haven't checked again what it is but assuming its the same thing, and the car is running like crap again. Any ideas on what I could try or do to fix this issue would be great?
Also my friend is having troubles with his cav, running turbo, full set-up pretty much the same as mine. His car will rev up and idle constantly at 2500rpms out of gear? He told me to say he has checked for intake leaks and has none, and we cannot figure out what may be causing this? thanks

Agreed. You need to have a wideband.
Get rid of the FMU and get tuned on something decent.
And maybe its possible that you killed an o2 sensor... Boost does that sometimes.

so nobody can help without me having a wideband and giving you numbers? So is there a different type of 02 sensor you can get or what?

Well... once you're dealing with HPT and you're on a wideband, your factory o2 sensor really won't matter. You'll want the wideband o2 sensor on your downpipe away from the turbo.
