My service rep at my dealership has been top notch , but when I take it in Ill allready have info on compression to compare with what they find. Good luck fft

List that info on the compresssion #'s. if you get a chance .
It should be easy to access the plugs,I have a compression tester. 
Good info to keep on file ,that way when I hit 49,000 miles I could check it myself before the warranty expires.
Others  getting close to 50K could also test for peace of mind. 
Steve I bet you felt relaxed for a couple hours there.
