Future damage if always set on 100hp?

[Dawgman]

I have a 2005 F250. Been using the Predator for about 2 years. I seem to get better fuel mileage when the setting is on 100hp. I do have 4 inch exhaust, and maintain a "steady" foot....usually

Are there any long term effects if kept on this setting (engine damage, etc.)? I will not tow using this. Just like to use it for every day driving, commuting, and occasional highway trips.

Thanks!

As long as you are not towing, and keep your foot out of it, you should be fine.

Thanks
