you should run the the Chall twice for sure , 1 pass each to get a feel of running it
The fun of running it down the track isn't how your car stacks up against the car in the other lane, it is the thrill of a 1/4 mile full throttle pass. If you enjoy full throttle jaunts on the street, you will absolutely love the strip.
Plus it gives you the opportunity to make a pass, change the tuning a little and assess the changes in the E.T. Let's you tune it up right instead of the old seat-of-the-pants deal of--"I think it runs better, but I'm not sure". When you are on the clock, you will know if the car liked the change or not.... Just my 0.02...
