2016 xp turbo, it doesn’t seem to have the power it did before, 426 miles on it, evo stage three ecu, plugs they recommended, evo atmospheric blow valve, been running evo ecu for about 400 miles with no problems, started while riding in Moab all of a sudden one day, pulled plugs and they look like this, is this normal for 400 miles? I do ride it hard but I let the turbo cool down for five to ten minutes before shutting off engine after every run, new to turbo engines so I have no clue if this is bad or not.
