Those air tabs can be helpful, but it takes testing to know whether how they are being deployed is helpful.
I 100% guarantee that there is a lot more to be gained on that truck without spending one red cent on VGs. For what the guy spent on VGs, he could have bought or made an air dam that likely does a lot better than what he has there.
Just the fact that his wide-open wheel well is still uncovered proves there's more gain to be had.
