P0300 Random cylinder misfire

Ok so I have an annoying P0300 happening during cold starts. Have a suspicion this may just be the nature of the beast with my mods. This seemed to start right after install of torque solution engine mounts. But has seemed to progressively get worse. I have attached 2 idle logs that show all cylinders displaying misfire conditions when cold. Once the engine is warm and all power pulls have reported 0 misfires. If anyone has any thoughts or experienced similar it would be appreciated.

In testing I have replaced PI’s and spark plugs. I have not done anything with DI’s or coils.

Mods are, AVO turbo, Light weight FW, DW700 injectors, NGK Racing plugs, torque solutions engine mounts, DT flex fuel, DT remote tuning.

Edit **It is a 2017 with 29k miles**
