This weekend I finaly got my #9 module to change my draw length from 28.5" to 30". Don't ask why but Pse dosn't ship my bow out with the 30" module. It has to be added by a proshop after they recieve it(don't ask why, It's stupid I know). So now my bow has the 30" dl that it's supposed to and my question is, Is it neccessary to retune my bow?

I have every intension of retuning but didn't know if it was really needed. I've always been under the assumption that after any adjustment is it neccessary to retune. What are your thoughts?
