okay, I just went to the track on Sunday. I ran two runs with the tailgate down and I lost 2 tenths every pass with the same launch and no spin. 15.82 with a bone stock ECSB Sierra with it up and 16.0 with it down. I proved it. Leave it up!!!

Thanks for the great test! :-) Kinda wierd how it runs better with it up! Too bad you didn't flat out take it off though...

Bingo, ever drive down the highway at 55/60 when it's raining, in my 8ft bed I really only get any drops in the last ft and even then it's not much.
