At that point (HFC added) I would throw in a tune.
First couple mods the car will respond and adjust but once you throw in HFC or TP you really starts throwing off the fuel and other items, the main idea behind the tune on the Z is to get everything back in check to be safe & reliable power. Also, it allows other options to be opened up, like better fan control, multiple maps, and more.
