Default Removing the cat Convertor

2013 Dyna Switchback. Bought the bike used. P.O. had installed a VH slip on exhaust and a high flow air cleaner. Bike came with a Fuel pack 3 tuner. Runs excellent.
I was given a complete stock exhaust off another Switchback. I removed the Cat Convertor and am planning on installing the head pipe without the cat.
My question is will I need to use the FP3 again or just leave it alone. Got the App for the FP3 downloaded to my android phone but am not the most tech savvy guy. Am a bit scared of the new technology. This is my first bike without a carburetor.
If it doesn't run right I can always put my head pipe with the cat back on.

You will need to retune it as removal of the cat changes the flow....once done your bike will run much cooler

You will be able to run your bike richer without ruining the cat. As a result it will run cooler. So definitely re tune it.
