Load cell issues

I am at work and cant take a photo
the load cell is from honkong. A voltage regulator and amplifier.

It puts out o to 4.3v, 9 ma current
I am getting the full 4.3v at full excitation (hope thats a word)
I have the output in A0 and i am using the example sketch for reading and printing an analog value
i need to increase the "span" between 0 output and desired output
