Well something very basic here I did that worked well.  I noticed the throttle cable had some slack in it right where it comes out of the adjuster and onto the throttle arm, I loosened the two adjustment screws and took the slack out.  I also took out the spacer nut on the firewall brace that only allows the throttle to be pushed so far, now I get a little more throttle when I step down on her, between these two adjustments it feels like a new truck, not kidding you.
