ATT Fun Video

I've been on the fence about getting this turbo to aid pulling my new camper and now am very curious about the "experimental" housing.

Do tell.
 
Wow that was a lot of smoke in the video! Is that an n/a 6.5? No im just kidding.

Good luck with that larger exhaust housing.
 
I noticed such a reduction in back pressure swapping from the GM-3 to the ATT. I don't have a test gauge for it but I will give my explanation for why I think this. When I was running the GM-3 I would notice it performed best at somewhere between 1/2 and 3/4 throttle. It was like any more fuel and it was overloading that damn tiny housing. I would be accelerating with the GM-3 at about 3/4 throttle and if I went to full throttle, it acted like it wasn't getting any more fuel at all. Boost went up but power went nowhere. With the ATT if I am accelerating at 3/4 throttle and punch it, it acts like it is getting more fuel and power increases. The housing flows so much better and smoother and really increased my top end.
