Engine Misfire at HI rpm

[flyingfin]

Engine Misfire at Hi RPM but i'm not sure is the Fuet Cut. MY ECU+ Give me MAF input 2300HZ and output signal 1900HZ but the engine misfire at 6000RPM in first gear and 5500RPM in second 5000RPM in third. But the MAF never indicate more than 2300HZ on the input signal and never over 1900 on the output signal. HELP ME PLEASE

Would be helpful if you filled out your vehicle profile with relevant mods.

Some common causes:
- Over richness at that RPM/Airflow (adjust via AFC)
- plugs fouled or not properly gapped (don't use platinum plugs for Turbo DSMs)
- plug wires bad
- boost leak (would cause over richness)
