The car has the stuff to run 9s @ 140. It doesn't seem to respond to changes in boost and timing. It probably isn't a can issue I'm just out of ideas. Next step will probably be a part out.

speed inc Tu1, its perfect.
Its not too agressive( IE 600+ lift) but just agressive enough. Valvetrain will be stable at its intended RPM range and easier to tune with, rather than a gnarley *** cam.
Just my $2 dollar bill

This is my favorite, followed by the TU1.
My own cam testing, as well as INTM8's, showed that reverse-splits don't work that well. I lost power going from a 224/236 to a 224/224. He gained power every time he added overlap. Both of these test results go against the "common logic" of turbo cam choice.

I've never seen a back-to-back dyno test where a reverse-split gained power over a conventional split. I have seen the opposite.
