Today I took the car on the highway and I noticed a slight drone at about 1700-1900 RPM.
Since I usually drive my Camaro on weekends and mostly do city driving I hadn't noticed this before. 1700-1900 is around 70 mph. It seams to be fine up to 67 and past 73 mph.
Doesn't bother me or the wife I just crank up the XM Lol, but figured I should mention it thought.
