Impressive results. Whats up with the torque though? I would expect it to make more.

my torque was a bit higher with my somewhat similar setup as seen in my graph below, very nice numbers, any chance in putting in some c16 and cranking the boost to about 20?

The torque is low due to the gear and converter slip.
