Turbo seems to boost okay(Is this how it should act?)
I don't know if this is how a 944 Turbo should act, but When you go wide open on it boosts up to 1.5 bar then the closer you get to redline it starts to bleed off, and at 6,000 RPM its at about 1.1 or 1.2 Bar. Is that right? Just wanting to make sure as I have a new to me diverter valve. It is a Forge one. Just making sure its working properly. The car seems to run a little better than it has been lately after replacing that. Seems to pull harder.

No, it should be a bit higher.
On my Turbo S, it boosts up to 2 bar on initial, then drops off to about 1.75 bar at red line.
Even for a regular turbo, I'd expect the initial boost to be pretty close to 2 (maybe 1.8 bar) then taper off to about 1.6 bar.

Or get rid of the intake/vacuum leaks... or get rid of the exhaust leaks... or make sure the cycling valve is functioning properly... or make sure the BOV is functioning properly... or make sure the turbo vanes are in good shape.

I think I may be reading the gauge incorrectly. I just replaced the stock Diverter Valve with a Forgee 007 that was off a Audi 1.8 LTR. Seems to be in good shape. Spring hold tension. Not sure what boost it set for.
How would I check for a working cycling valve?
Exhaust leaks could be a problem since my cat and what not is jerry rigged. I will be replacing that with a test pipe.
I will be looking at redoing the vacuum lines with a venturi delete, but right now I need to focus on an alignment and tires.

There's probably something up if it acts like you describe. Probably not your diverter valve, though. Also, usually not the wastegate either.
