Was the "blip" with no load on the motor, or while the vehicle is in motion? If it stumbles or bogs with no load, then the setup is farther off.

You are correct about perhaps needing more cam lift above half-throttle. Note though that a smaller squirter will extend the duration of the pump shot. I still feel it is best to get the right cam first, and then fine tune with the squirter.

The chart you posted is helpful but does not show the effect of the two cam positions. If your motor is fine just off idle, you can try your current cam in the other position so that the lift occurs at higher throttle position degrees.
