| it really differs truck to truck,i ran the bully dog triple dog and it ran great but i didn't in crease my economy so i switch to the ppe and it had the same power and more on the higher settings but it increased my fuel economy by 3 to 4 mpg providing that i drive right....i found out on my trucks i get the best economy running an extra 90hp....just my experience..good luck on your new toys
