955 Turbo misfiring when pulling away after warm start

I wondered if anyone had any ideas on a mis fire I have on a 955 Turbo?

From cold it seems fine, but after a short drive, say a mile, if I shut down then start it back up 5 minutes or so later, I get a misfire when pulling away. It clears after a couple of seconds as I get the revs up, then is fine for the rest of the journey, even stopping and pulling away from lights etc.

Plugs and coils are only a couple of thousand miles old and were BERU.
No EML light comes on.

It seems to happen worse, if I pull away going around a corner.

Not sure if related, but I have a new harness for the transmission as about 6 months ago, the transmission lights all came on and the change was clunky.
The wiring harness wicks fluid up the inside of the cable and it eventually causes shorts on the connectors and causes issues. I cleaned the connectors and it was fine for 6 months.
I recently cleaned the connectors again and they weren't that wet to be honest, but this is on my list of jobs, along with adding a tube of anti shudder fix, which worked wonders on my old 7 series BMW transmission.
 
usual logic are coil packs but this behaviour is odd, fueling issue?
