OK I have read so much this last weekend on Coolant Temps. Everyone reports around town temps higher like 210-230. Mine are opposite. 220-230 on freeway and 190-200 around town. This normal? If not suggestions?

Well I have an electric water pump and I had to rewire it as the relays and wires were bad. I should have stated this is only when its 90F + out. This morning to work it was 186 to 190 freeway. But when I came home from work friday it was 95 outside and it was 229. As soon as I got off the freeway and hit the first light it drooped fast to 205.

I made sure all fans are working. I did not take apart to see if debris was in between as I need to do more research on doing this with a supercharger. New coolant.

Hmm, since you're getting "reversed" temps, higher temps at higher speed, I'd suggest you do a "cleanout" of your radiator. A ton of threads on this particular subject here on the forum. Sure sounds like the more your engine is working, the hotter it's getting and that's usually a sign of a clogged up radiator. Read this thread and see if it applies to you.
