I have that tach in the Duster. I like it because it's easy to use and replays the run in 1/3 time so you can see what you did on the burnout , what you really shifted at(compared to what chip you may have used), and what you crossed the finish line at.

It will record for 80 or 90 seconds, plenty of time to start it for your burnout...... if you remember to turn it on!
