So far my impression is these turbos are NOT too small for this application. It's so eager to downshift it's hard to tell, but giving it a 1/2 throttle squeeze in drive brings on the boost pretty quick, but it is not instant or light switch. It feels just like I'd want it to really, so it may all turn out quite well. Because of the downshift it's hard to tell yet where the boost threshold is, but it seems to be somewhere around 2200-2400.

I did weld in a bung to do back pressure testing, I want to do that this fall as well to see where it's at.
