Got just basic weights on my F150 hitched up

I've lit mine up several times too, and I don't have near the torque you do. I know I have it set up pretty well. I wouldn't use that as your barometer. That trailer may have a good bit of tongue weight on the rear tires, but it also acts like a giant wheelie bar. Normally when you do a hole shot, the weight transfers back onto the drive wheels, but with the trailer attached, it has a harder time doing that, so harder to get the tires to bite.
