You Do have the RFD? Did you get the updated tuning flashed for this? Seems I'm seeing common issues with people who have the RFD mod.

here are the update for today, sharing with you

action taken:
1> unplug the maf sensor/ issue still exist but better (misfire counter drop from 50 to 20,idle rpm much stable)
2> find that most of the misfires come from C3, a little from C2 and C4
3> then, change the coilpack of C3 and C1--no help
4> change the spark plug of C3 and C1--better (ecu detect less misfire, but still can hear and feel car stuck a little bit around 6000 RPM)

so what should be my next actions?:

1. checking injectors ?
2. put stock maf back?
3. BTW: i use apr downpipe and stock cat-back, will it be the flow limitation then cause
misfires, why most misfire only come from C3?
4. Or misfire like 50 to 60 can be safely ingored?

waitting for your comments...

appreciate it.

Run the stock MAF and report back. Every time you make a change clear the codes to force the ECU to re adapt. You should be driving it for a good 10-15 miles so the adaptations can take place.
