do the nfl 100s lose the starting xfactor when you power them up

ok, thanks

You have to add the “x factor 100” and it will be active.

so to be clear, if i power them up, when they start the game  the x factor will not be active?

Yes but everything that comes with powering a player up is better imo

but After power up do they still start the game off on fire?

You just have to add it back when you power them up, but it will cost training. It is similar to how the Superstar promo players worked when you powered them up.
