Ive never had it on lvl 3. I leave it on lvl 2 for the extra towing power and to correct the tire size. Im fixin to leave out on a 330 mile one way trip towin the zuk. Just curious if i used lvl 3 if i would hurt anything since im towin. Just thinkin a lil extra power might help. I run 93 octane in the truck so i know im not gonna have to worry about that. Just would like to hear some thoughts on it.
im on level 3 now, i use it to go from school 4 hours back home and i get a little better mileage. and yes it hauls ass lol
see thats what i was wondering bout it... i know its a lil more power so i thought it might help and maybe help the mpgs
Its really not that much of a difference (at least I never noticed it when I had the Edge previously). Its a performance tune for higher octane, no biggie. I run a custom performance tune at all times except when towing.
I ran my custom perf 91 (no 93 up here) all summer. You'll notice a difference from level 2 for sure, but don't really see it hurting anything if you're towing.
