Misfire
After putting big turbos and true turbo Pipes in my E63 and starting it, it makes misfire failure. New plugs installed and ignition coils are also okey
No failure with MB Diagnostic and the values of camshaft chain timing is also ok
What could Be the failure?

2014 E63S; AMS 100 octane ECU dyno tune; EDOK TCU tune; BB intakes; sprintbooster
Also check all wires to the electrical ignition system in the engine... One may be loose at the cylinders in question
How often are you having misfires and which cylinders

Do the misfires happen under load/ boost? Or at any time ie idle or part throttle? If using stock plugs gap them lower. Stock gap is at .032 needs to be closer to .022.

Sorry to hear that. From what I understand, the Biturbo E63 mostly have misfire either because it's tuned or the spark plugs are dirty.
I just got a full B service and purchased new Weistec plug during the service and a member advised to gap it at .022 which I had my dealer do and I even took photos of the gapping at .022. I don't want to say my car runs stronger with just the spark plug change, but it definitely ran strong with a full service including transmission and LSD change.
What kind of misfire codes are display when it happened and which tuner you went with for your turbo upgrade? I would check with your tuner first to see what is going on. More experienced tuners go through the development process seeing misfire and might be able to pinpoint it better.
Good luck.

If it's misfiring not under load, then probably not spark blow out? Is it throwing codes for which cylinders? What exactly are you experiencing? Can you log boost or timing? Bigger turbos will certainly need colder plugs gapped to .022 ish to run right under load, but even stock plugs should work idle and part throttle.
