Default getting boost

I have read the adjusting/moding the afc and the smoke screw but with my setup currently I get very little boost maybe 10 psi max if I hammer it
the egts when in overdrive get to 1100 leveled off in the other gears are about 700-800

how can I get more boost? without killing my egts?
this isnt even towing anything

thanks
