Same thing as everyone, the new car is tricky. There is so little you can do, that when you do find something, it is huge. For instance the 18 car earlier in the year, and now the Roush cars. What used to be a little something is allot now!
We had them covered last year, but racing both cars we spent allot of time trying to lock up the Championship instead of working on just the new car more, and it has showed this year. We have good speed and usualy qual. well, it's just getting them to stay that way all day long.
I think the Dodge boy's had the old car down, especialy on the Intermediate tracks (1.5-2mi). The new car is a whole differant game, and if you are a little off your down laps in a hurry!
