AJ tuning Brittney's Monster car is a good thing, and we can be fairly certain she will find herself on the winner's platform before season's end.
But lets not forget, as incredibly talented as AJ is, he did struggle last season. Some would say it was funding, and I wouldn't disagree, but as has been discussed ad nauseum, he does build a lot of his own stuff. Still, with secure financing and the ability to push the envelope again, I suspect he will teach Brittney everything she needs to win in Top Fuel.
It remains to be seen if she has what it takes to compete with the DSR Top Fuel juggernaut on a consistent basis though... and we know she won't get replaced. I'm not suggesting she's not a quality driver, I'm merely stating that Tony & Antron have demonstrated they are at their best when the pressure is at it's peak. She may be able to do that too, we just don't know. Still, she has her daddy's blood runnin' through her veins, so it is possible.
