Changed plugs, still having issues
So I was having bad Sputter under throttle at 4-5k. Swapped plugs out, they were FOULED. Put in some new NGK BPR8es gapped at 25. Still having an issue. I'm worried it could be something serious. Mods are ahem tru boost/wide band and oil pressure gauges..buschur 3 inch exhaust no cat, Megan exhaust manifold, forge recirculation valve, k&n filter, ets intercooler and mini battery, gsc S2 cams. And a few others. Car has CEL for system rich. Any help?

How rich is your car running ? What are you afr's on your wideband ?It maybe possible that if your car is running to rich that could making it sputter and break up. I would get the rich issue ironed out first and then go from there.

Idk how cold it gets where you live, but 25 seems like too big of a gap, at least for the winter time. Try going to 21, I pulled my plugs last week and dropped one had same problem. Set all plugs to like 16. No more issues.
