That's good to know, I asked this question here the other day: How do you do a proper dyno comparison?

Funny how opinions and wrong info can turn into fact on message boards. Several people in other threads have been saying that the car will get faster and dyno higher after 20-60 miles. Which led me to start that thread. Dynoing would be a real pain if you to drive it around for awhile after each mod.
