Assuming the plugs are ok and after trying another set....
Check your AFR just before the missfire occurs ....
(not when its happening as this will show up as rich)
Dont know DTA in detail but can you adjust the coil dwell time ?

Cant read the text in that picture.
As you are running coil pack, the dwell time can be increased alot to
increase plug voltage. (this only works to a limit).
Do you know what the dwell time is at the RPM (not boost) that the
missfire happens at ?

I would expect to see at least 6 to 8 milliseconds over 3500 rpm on a
coilpack. Try increasing the value if you can change it but you may
need to consult dta as values that are too large can burns the coils out.
