 File 2023-06-26 17_37_21 IJE0S IJE0S+ 17T 3.5 v14 - WBAUC73568VF25247_FF.mhdPull at the beginning again feels awesome up to 6500 where 6 still misfires. Looks like the boost spike is much reduced at the end, but still goes up a little? Also, why are my RPM's so spikey? Is my transmission or differential slipping / getting ready to go out?

2023-06-11 13_15_40 IJE0S IJE0S+ 17T 3.5 v11 - WBAUC73568VF25247_FF.mhd_.csv Fixed cyl 4 misfire by swapping cly 4 & 3 injectors w/ new seals/gaskets. Cly 4 in was kind of loose and easy to pull out and push in new seal. Car feels strong, but virtual dyno numbers look low to me on a flat road in 3rd (13_15_40 timestamp). Anything else we can adjust here or do you think I'm at my limit with this setup? I'd like to schedule some pulls on a local dyno to confirm numbers if you think everything is looking OK now.

2023-06-03 15_46_13 IJE0S IJE0S+ 17T 3.5 v11 - WBAUC73568VF25247_FF bimmerlife harness and modified R8 coils installed. Everything was looking good on V12 low boost map, but then when I went back to higher boost V11 cyl 4 kept misfiring on the old .016 gapped 97968 plugs. So I installed new .018 gapped 97968 plugs, but still keep misfiring on cyl 4. I tried swapping coils and harness connectors, but still kept misfiring on cyl 4.
Should I get some 97506 plugs and gap them the same and try? Or run a tank of techron cleaner through? I'm running out of ideas.
