xzt+ fuel mileage
my dad says his truck gets better fuel mileage on the performance setting than the economy. is this common? his truck is a 99 with the auto, muffler deleted and k&n stock replacement.

Mine seems to get better mpg on performance setting as well. I attribute this to not using as much throttle to get the same mph up the hills as when on timing only or off. The hills I have to go up to get home from work are 6%, one of which is 12 miles. Maybe I'm just blowing smoke out my butt, who knows?

I'm running the HRVP-44 tune and in L3 (timming & fueling) I'm seeing 14.8 to 16.6 mpg. On L2 (timming only) I'm seeing 17 mpg and better. Of course 99% of the time I'm on L3, so i don't have a lot of data on L2. These are all un-loaded, driving on I-15 up and down several grades per day.
I just up-loaded the newest version of the Aggressive Tune, so I'll be checking the mileage on that.

I've re-filled the tank and will run in the mileage mode for awhile. I'll post something when the results are in.
