I run what I think is called "Looney extreme track file"....can't remember...lol...and I run it 100% all day , every day.
DJ will only send a file that your truck can handle....so tell him your mods so you can get the appropriate looney.
If you only have exhaust and intake,...he'll only send the "generic" Looney,...because he wants to keep you in the safe ranges of your vehicle.
Every time you change something on your truck,...let them know..
I remember 2 years ago,....when I got my first "Looney",..I smiled for days....then down the road I added some other go fast goodies..... I smile a lot harder now....lol
