24psi - 16* of timing
The SST - It's a little too tight as you can tell, but I plan on going to an L33 or a 6L so I think with the added displacement it will stall where I want it to so I'm not going to mess with the stall on the 4.8

How is your th400 setup?Full manual valve body or what? I just swapped my t56 for a th400 that has a fresh rebuild. I'm trying to figure out what I want to do about my trans setup. It doesn't like boost at all. Mine is stock valve body right now and in 1st gear it shifts by itself. When under boost I hit the rev limiter. Just ordered a transgo th400 1-2 kit and the trans go boost bypass valve.

A little 4.8... well done!!
I'd get rid of that transgo crap and get a decent complete remanufactured full manual valve body. I have a Turbo Action fmrvb in my t400, shifts instant. I think I better put an aluminum drum in it next for safety.

Nothing fancy.
