Blues are old with 18g, greens are 28r with skunk2 intake. Boost spiked to 21 pounds at first and falls off to roughly 17. Im thinking my exhaust manifold (greddy) is keeping flow down up top. Gonna try duty % by rpm to try and make it smooth the whole way.

Heres a better graph with just the new stuff.

Nice! Makes me want to replace my 18G! Very interesting HP curve, it looks like it still wanted to climb after 5000, im no expert, but I'd suspect the greddy exhaust manifold could be the restriction.
