Viberation and flash issues
I have a I have a constant viberation at 70 to 80mph highway speeds. You can actaully hear it! I know about the drone viberation at 1500 to 2000 RPM's but I know have it at 2500 PRM's. I am afraid to have the engine flashed because my dealer told me that the new flash ( I have not had it flashed since I bought it in Nov. 03) would also change the downshift pattern of my transmission. Help please

not Speed
I just drove about 2400 miles and 95% was interstate. It is definately not just speed it seems to be engine RPM and the load on the engine. Anopther interesting thing is that the lower RPM drone gets much worse in very cold weather.
