Class6 has similar advise as I and maybe explained it better. Small adjustments of trim to bring the bow up and only use tabs if required to level the boat. Many times when I run with just one on board the port tab is down a little when I pull her out on the trailer. This is do too the roll the boat has from a right hand prop and weight on port side. When I run solo no tab required to stay level; my weight balances the roll from the prop torque. I find with a 3 blade you can easily over trim and the boat can become vary loose. With the 4 blade Rev 4 I can trim to the moon and the boat just slows down if I over trim. Again, you should not need tabs to keep the boat from porpoising... The lead weight idea works well if you feal the need to run wild in rough water. It keeps the bow down without using lots of tab and scrubbing speed...

Do you have indicators on the tabs. Have you ever run the boat wher you feel comfortable and don't move the tabs. Take it out of the water and see where they really are compared to level. Maybe your just running too much tab keeping the bow down and lifting the rear up out of the water. I would start a run. Tabs up all the way keep the drive trim in and trim up to level only. Do it very little at a time and give the boat time to react and settle at each stap of the button. Check and mark that adjustment also. So you really know where level is. Last thing. Bravo drive. If it's a newer model with ecentric adjustment at rear ram connection. Make sure it's at the most rear setting. This often gets moved when taking the drive off. Let us know how it goes.
I appreciate everyone's input here.

I realize your a pilot , so this may sound like a dumb question. Have you checked trim tab wiring,( are you sure they are going the direction indicated on switch?) Tabs down with drive trimmed up will cause bow lift ,then nose dive.Good Luck!!!

Sorry Man, it should not be this hard to run...
The boat will porpoise with out using the tabs at lower speeds no matter where I start or end with the trim. At around 40 mph I can raise the tabs all the way up (in calm water), until I get into the low 60's, where it starts a violent porpoise. In order to run in the 60's, I need tabs, unless I have the boat weighted just right I haven't yet figured out how much weight and where though.
I appreciate everyone's input here.
