Went to the dealer to have my speedo calibrated for my 265's. Anybody know how to check if they actually did it right or not? At 65 mph I was turning just under 2000 rpms, and at 70 I was just under 2100.

Use a GPS

That would be great if I could get my hands on one.

Mile markers. 60 miles per hour = 1 mile in 1 minute.
