for my 3B audi build, I've been considering a 4088 heavily.
Now that I see the 4094, I'm very, very interested in it as well.
I see that the 4088 and the 4094 have the same turbine size, but the 4094 has a bigger comp size.
I would suspect they spool similarly?
Also, I see that you have some T67's. Do you also offer a T67 dbb (aka T04Z)? I'd be interested in something like that as well.
Hope all is well
