380rwhp run was the old hks cast manifold @ 15psi. The 450rwhp run was his new setup @ 18psi with meth injection. He does have a graph for 15psi on the new setup without meth on for a comparison and our turbo kit was worth 35rwhp in addition to the loss of rerouting the wastegate. That alone is usually 15-20rwhp.
The below run does demonstrate the difference in " spool " between the two setups. Keep in mind it would be a lot more if we kept the same turbine a/r( old 380rwhp was .84 new setup has 1.15) However he intends to run 20psi and its much safer with the bigger a/r.
He has some problems with the wastegate spring at the higher rpms and not having a pill in the map sensor line on the microtech; you can see the wavvy lines in the high rpms.
I edited one run out of this dyno graph with MS paint to make things more clear.
