Quick Question about 7180 Predator

[MAXPOWER]

Do I have to remove the fuses when I change from tune to tune? I run on the 65 but change to the tow tune now and then. Only because I pull a fifth wheel. Also, I have a K&N cold air intake in the truck but the rest is all stock. (exhaust etc.) Can I run the 85 or 120 once and a while without hurting anything? 2003 3500 4x4 dually. Thanks

I don't ever take out the fuses going from one tune to another, but DiabloSport may say other wise.

I run the 120 tune everyday, but do remember don't beat on it or else you will limp the tranny. Also I would not tow your fifth wheel with the 85 or 120 tunes.
