Ahh... I'm still on a stock TB. And you look to be moving air much better.

Actually......I stand corrected. 9.17 lower and 3.75 upper. I forgot we changed uppers from 3.25 to 3.75 when we swapped lowers. The 3.25 with 9.17 made too much boost for my setup. Ended up with around 12 lbs of boost with the 3.75.
