Its strange that after driving somewhat hard on the highway then going back to normal driving on side streets it goes away for a while then comes back. I really notice it between 1000 and 2000 RPM's. I would agree with them thats it normal if it did it from day one but it has recently just started.

Im still waiting to hear back from my foreman but don't expect to get many answers. It doesn't seem to be affecting performance but it sure is annoying.
