One thing to realize is that there are several forms of PID equations commonly used. Asking for help tuning without specifying the form can lead to misleading answers. See the attached picture for the equations of common forms (as defined in the LabVIEW help). Wikipedia calls the Academic form the standard form, the the Parallel form the Ideal Parallel form.

LabVIEW uses the academic form, however, I think most people answering your questions are using the parallel form.

For example, to make the integral term have more effect, you increase the integral constant in the parallel form, or make it smaller in the Academic form.
