This is the set up I'm going to run this year.

Agressor 9 vane bowl, AA Impeller, Place Diverter HP Steering Nozzle & new style Place Diverter.

Ran 88mph with stock steering nozzle, 86mph with Place Diverter full Droop, 85mph with Place Diverter HP Steering Nozzle. Same stretch of river with weight very close in boat. I know that 3mph could be anything. The stock steering nozzle feels quicker and the main difference is it narrows much quicker than the droop & HP nozzle.

My thought is a nozzle wedge. I don't want to put to much pressure in the bowl, I'm sure I can shrink it safely a little. My neighbor at the river who has a blown alcohol hydro mentioned the old Agressor bowls blew holes in the upper middle area. Hope I didn't get one of those 

Any thoughts form those who have experimented with these would be appreciated?

I took my wedge out and added a ride plate(boat had a previous porpoise problem @ 35-50), still have the wedge for future tuning.

One thing all this jaw jacking doesn't do, is produce results.
Do your homework, and try it out.
one thing that IS a given is that no matter whos boat has what hardware, no 2 boats will react exactly the same.
