Missfire at high RPM
Over the past few months I have been working with a highly suggested remote tuner. He has asked me to take my car to a mechanic to figure out my missfire that I'm seeing in my logs at high RPM. I would like to figure this out on my own rather than having a mechanic dig into it. My mods are down pipe, up pipe, tial ewg, ebc, fpr, Cobb intake. I'm showing cylinder roughness on cylinder 2 for the most part. I changed spark plugs and swapped coils 2/4. Any ideas are greatly appreciated.

What does cylinder roughness mean? Can you post up a link to the log files?

You could compression test it. Swap around injectors, and check resistance of the wires.
