You can get used to it though. Guys were putting a GTX 35 on a 2.5 liter 8.2:1 compression 4 banger EJ257 and calling it streetable. It’s just a different animal.
They have to be doing something significant to that housing.

Their dyno graph agrees with you:

Big torque spike around 3,200 RPM. Max torque looks to be around ~5,300 RPM.
I shift very early in my 6MT, like 2 - 2.5k RPM most times (I sound like a douche revving it out to 3k to shift with my exhaust setup) and this would for sure be detrimental to my mostly urban driving. Also not a fan of the binary on/off that a lot of big turbos present. Rip motor mounts lol.
