Default quick utec upgrade question

I am currently running a full stage 4 with/ fmic and vf22. I'd like to upgrade my drive pulley with a perrin pulley. The question is do I need to go back to the shop that did my tuning after I install it or will it not make a difference to the utec? thanks for the help.

No retune needed but the lightened pully wheels sometimes trigger the ecu misrire codes. Just an FYI. As far as I am aware you can't do anything to inhibite these codes.
