Problems With NonlinearRegress

Has anyone experienced any problems with using the NonlinearRegress function
with large functions with many parameters - I am experiencing a problem
using this function when solving for many parameters in a large model (the
function which these parameters appear in over two pages long!!) -
NonlinearRegress solves for the parameters fine and pushes out a
SinglePredictionCITable that makes sence but if I use the BestFitParameters
back in the original function to generate a table to match the predicted
values they are not identical.
Tried all avenues of decimal places and accuracy and such to no avail - can
anyone help on this one?
