Spark Plugs with JB4?

[PFMUSTANG]

Hey guys,
I have a 2024 2.3L Bronco 7MT. Currently installed is a K&N CAI, BOV Spacer, Throttle controller and Borla Touring Axleback. I was looking to purchase the JB4 piggyback and was curious if most guys with that are running the one step colder 6510 NGK spark plugs. Wanted some insight on if guys with the piggyback tuners prefer their stock plugs or colder plugs with a tighter gap, thanks!

One range colder. You'll notice for sure. I haven't done them on the Bronco yet. Once I do the Procal I will. They helped with idle, response, and economy on my 3.5 F150 post tune.
