I agree, the weather is no help. I never even go to the track in the summer except for special events. As for the weight of the truck, look around here. 5500lbs is fairly normal.

Last night it ran a 10.2 @ 71mph (with no spare tire also). I was freakin pissed, since last summers runs i added a 93oct blackbear tune and vette servo and took out the 3rd row. The truck feels much faster than last year so i was shooting for a 9.7. But didnt get it. Guess im asking too much out of a 5500 pound truck. Anyways just wanted to share the experience.

Dude...its the weather. I just ran and lost 5 mph and 7 Tenths ET. You need the cold-dry air...about 42 degrees for max hp. Don't sweat it !!
