FBO pure turbo stage 1 335i

Car sat for 5 months, and started throwing random check engine lights after the sit. I thought it was the fuel, but after a few tanks it wasn't. Noticed it would throw a CEL @ 5.5-6k rpms wot. So I decided to change the plugs, ngk laser iridium's -1 .. which were the same ones that were in the car. old ones didn't look fouled once pulled.I gapped them to .22

Drove the car, once again got a cell (sometimes) for a camshaft sensor, intake. So while waiting for the part I cleaned my vanos solenoids. I Swapped the sensor today and idle and driving is perfect. Car pulls hard, but now around 6k the car misfires cylinder 1 & 3. Prior to today, never got a misfire in any cylinder. I am stumped and don't know what else to do. AFR is digital using jb4 and the car isn't running lean. Fuel pressure L/H is perfect.

Update: swapped coils from other cyls and still misfires cylinder 1&3 so it's not the coils. Not sure where to go at this point. Might have to bring it somewhere.

Someone help

I'm assuming you're logging the pulls since you "know" fuel pressure is "perfect". Post the logs for people to review.
