Angry F22 misfire under load BM3 stage1 ACN91

2016 F22 N26 91k miles - been stage 1 since 70k. Drove to work this morning perfectly fine. Car sat for 8 hours as it usually does. Got in warmed it up ( live in southern CA didn’t take long) first stop sign take off I noticed sluggish boost. Taking note I drove carefully to fully warm up the car. From Stop under load the car will misfire, shutter I hear exhaust notes of skipping. Pull over put it P. Revs perfect… quick rev slow rev all good.
Under load in comfort/sport/sport + cannot give the beans at all. Even a slow roll into 4-4500 rpm it will misfire etc…
Now I had the plugs and injectors done 2 weeks ago car drove amazing.
I’m on stage 1 ACN91 Bootmod3. Gamma down pipe, Dinan coil packs 20k ago. NGK plugs, OEM injectors, AFE intake , MPE off f30, aluminum trans pan and new fluid 5k ago. M3 LCA, AFE FMIC,
Bad battery? Bad DME? Coil packs? I will attach the data-logging from boomod
It looks wild and I’ve sent email to PTF already. Any help is appreciated greatly!
