Just raced an eco boost off a light, 95% sure it was a 6 speed as well. The thing slowly pulled away from me. Bone stock crew cab and a girl driving to boot. Even with some minor bolt ons and 3.92 gears I can't hang. Sad to say but I think the new 10 speed 5.0 might be my next truck. I lost to them on the 1/4 every time as well. Wish there was a way to make these trucks quicker without dropping 10k+ on boosting it.
