I was wondering the same thing about the testing of the ATT
all it takes is A Ateam to arrive at my door, I just towed from NC to Ohio on 77 today, pretty much all mountains from VA North, I could maintain 55 on the worst grades EGTs hit 1150, 3rd Gear on the long pulls, Plenty good for me about 200% better than stock setup, The Turbo Controller I made is working very well about 4 Psi on the level tops out at 18 Psi, I put a softer spring in it before this trip
