I took all my measurements with DL with me in the truck, including t/a, but I'm really not blocking any speakers physically. My dash widebands aren't, my sub right behind the seat isn't, possibly the left door midbass is by my leg to a degree, but overall, the tuning seems very good. Of course all eq is done with me in it too.

If I could be sure to have the mic in the exact same spot, it would be interesting to see if the t/a stayed the same with me in it vs not.
