Highway rpms?

[Djd085]

My 04 lb7 runs over 2k rpms at 70mph. Everyone I talk to says they run under 2k. Could my cluster just be messed up?

That all depends on tire size and if the person telling you that has a 5 or 6 speed transmission. Unless the cluster says 3000 and the engine is just chugging along I wouldn't worry.

If you are running stock tires (245/75R16), you should be doing just slightly above 2k RPM at 70.
