yes ive used a tr. yes, a TR will give 30 hp or so over a dialed hot 4 barrel. the TR manifolds do not produce good velocities at reasonable street rpms. if your using hi 4000 stalls or 5 series ring gears, i dont associate those with streetable components. your combination tells me enough of whats going on.

you cannot drive around at 4000 rpms all tunnel ram and headers. the cops will pull you over.

-no a 4000 stall doesnt lock up at 4000 exactly. it does mean your not cruising at 2200 anymore.
