Slacken the lock nut on the arm, pull out the split pin, pop off the arm. Now twist the end of arm clockwise to tighten - go one thread at a time. Reverse the instructions. Oh, its a good idea to let the turbo cool down before you touch it!

I have the said problem, will tightening the arm actually stop the rattling or just up the boost?

I have found the following as a good guide:

but don't want to mess around with the boost...
