I can't build more than 2-3 lbs boost when power-braking. I get to 2-3 lbs pretty fast and the motor sounds like it bogs. Sometimes if I keep it gassed for ten seconds or so, it will go higher, but not always and takes longer than it should.

Here is my new combo: New TE62, RJC boost controller & power plate, 50lb injectors, Armstrong 93 chip, 9 1/2 multi disk converter (0 stall speed... my understanding this was 3000-3200 rpm)), with pump kit. TH downpipe, 3 inch single shot.

Normal driving the boost comes up pretty good. The boost is set at 16, which is the lowest I can set it, under full throttle with the boost controller all the way out, and the accuator pulled 1/32nd of an inch or less. I'm waiting for my alky kit to turn it up.

Another problem I noticed is that with the 9 1/5 converter and pump kit, the 2-3 shift is no longer crisp...there is a short flare, or hesitation and rise in RPM's that was not there before.
 
With the accuator rod only pulled out less then 1/32" your puck might not be seated. I think that RJC recomends puting them at 1/8".
 
It is a heavy duty accuator and I actually had it pulled over 1/8 with the same problem building boost, but loosened it cause the boost was at 17-18lbs and I was getting some detonation. I'll tighten it back to 1/8 and check it again. Waiting for Alky!
 
Check your RJC controller. You may have it set wrong. Mine was doing just that and I released some of the pressure and I got my boost back.

What's the fuel pressure at?

Fuel pressure is at 42 with the line off.

How do TPS and IAC effect the leaness and richness while power braking
 
It will only rev to 2000 RPM with a 3000+ stall converter?

I think you've found your problem.
