Me either until I added the extra power to the driveline. I also had significantly more miles so I would think at under 20K your guibo is probably not the issue. Mine would only do it under boost, but if you're saying 4K RPMs then that may not be the answer since boost doesn't come on until a little later with the centri if I'm not mistaken.
