Nice job... For comparison, I could only get about 390rwhp at 18psi with my SP61GT(using a CAT). I later did 451rwhp at 21psi. I have similar mods as you, so that goes to show that you have a healthy motor unlike mine.

I do miss how well my SP61GT spooled compared to my SP59 with a tubular manifold.
