Engine Stutter after Stage 2+

[MOBF10]

Hey guys, sorry if this is the wrong section for this but I'm desperately seeking assistance.

Car was bone stock 1k miles ago. Had the following installed all together:
-Arm DPs
-AA single midpipe
-one step colder plugs NKG .020 gap
-4pin crankhub
-MHD Stage 2+ flash

When running the stage 2+ e30 map I get engine stutter soon as I hit 6k rpm in any gear and no it's not the rev limiter. When I switch back to stage 2+ 91 the engine stutter isn't there. Anyone know what's happening? Do I need 2 step colder plugs? I'm narrowing this down to a spark plug issue but I'm not 100% sure. Anyone run into this?

Definitely sounds like a plug or coil issue are you seeing miss fires on all cylinders or just 1? K had this happen when one of my plugs went out of gap spec and caused terrible stuttering from 6k to redline, I replaced and regapped and it it went away
