Same cam, Same heads, only change was the removal of the PD blower and the install of the TT setup and a dyno tune for the new setup by the same tuner.
145 rwhp difference and a large chunk of that was due to the blowers drag.
Every Bit helps but turning a blower takes a LOT more rwhp than the electric pump will give you.

Do you have datalogs of this? Curious what the injector flow, airflow, and timing was at for both.
