How Do I Modify a Custom Tune?

I have a U7135 with a custom dynotune on my car, a 09 Challenger RT. I want to readjust my fan settings. Do I need to install the original tune first and then install the custom tune again and make the adjustments under Modify Tune? Or is there a way to adjust the fan settings without doing all this? I searched the forum but couldn't find what I was looking for. Thanks.

Depends if the tuner locked it or not.

I am aware of that. My question is do I need to install the original tune
first and then install the custom tune again and make the adjustments under Modify Tune?
Or is there a way to adjust the fan settings without doing all this?

just to be on the safe side , i would suggest returning it back to stock tune then do your normal tune selection then mod the parameters as to your liking then install that way there is no chance of it getting criss-crossed. I have had that happen on my ram--- and for my ram the only quick adjustments i can make is tire size , if i wanted to adjust i have to install the tune again. There is also the option of just reprogramming your car without installing the OE tune--- it would be quciker so you would basiclly reflash the pcm with your modded custom tune and you wont have to reinstall the stock tune
