is there anyone that has set a custom tune to get the most efficient gas mileage? keep on mind there is nothing but hilllls around here. thanks in advance

 

i've been getting the best mileage with this tune

lvl 3 93oct
1.5 timing advance
no change to standard shift points. play with other settings like wot shift points, wot fuel as these won't affect mileage under normal driving conditions.

It is also very hilly where i live and i get 15mpg average. It all depends on where i go and how i drive.
