Been tweaking my fuel pressure down to lean it out a bit and checked static and it was approx 6 psi differnce should i be worried or do i just have good vacuum?

Sounds right ...

6 psi = ~12.3 InHg

Most TRs will pull around that in Drive. At idle, depending on cam, altitude, etc. they usually pull about 13-14.5 InHg. I've noticed at higher altitude (like where I am ... ~5300 ft) it'll be reflected in lower idle vacuum.
