I can definitely feel the car hesitating when going WOT, almost as if it is misfiring, but less severe. Can hear what sounds like turbo sound going "PSH PSH PSH" until I throw limp mode. I will be replacing both oxygen sensors this week to see if O2 sensors could have something to do with this. Car is 100% stock except the ER CP. Running 91 OCT pump gas.

Sorry to revive an old thread, but did you or someone else had this problem and fixed it? Just bought my car and it does the same thing and it is driving me crazy!
