my car is an n54 and i have the pot set to 7 o'clock and worked first shot. took about 12 miles of driving for the cats to clear.
getting the DME plug out was a b*tch if it's your first time like me. it's mostly because of the tight space and a fear of breaking anything. it's hard to pull the brackets that allows it to release the DME wiring harness. then you've got to pull out the actual pin connector from the harness to get access to the wiring pins. you'll need a couple pick tools as the tabs and access are small.
make sure you pull the correct plug. i made the mistake of pulling the wrong one which was a big waste of time. the instructions weren't very specific on that part. pic of the correct connector below. it's located 2nd from the left in the row of connectors if you're facing towards the windshield.
don't forget to disconnect your battery. leave your trunk open if you don't have your valet key, otherwise you won't be able to open your trunk with no power.
