Installed my evo the other day ,i had a little problem and called the factory and we got it fixed, But they told me that to get the best mileage to use level 3, my only concern is as long as you keep your foot out of it nothing should get hurt (trans)I'm putting the transgo jr, in when iget it so i'm just checking with those that have more experience in this area thanks..

I actually get the best mileage with the Evolution in level 1. I think because so many things can affect fuel economy, your best to just try the different levels and see what works best for you and your driving style.

Just use caution and common sense and you shouldn't have any concerns with your trans.

I always got the best mileage with my Edje juice on level 5, used level 3 I think when towing
