Banks Power pack finally installed - WHAT A DIFFERENCE!!!

You check back with us in about a year and let us know what your costs are and what you're getting for mileage. Right now I suspect your driving it harder than you were because it has something "new" on it, I predict you will be disappointed in the near future when you actually put some miles on it and a few tanks of gas through it. I'm not just guessing or being negative I'm speaking from experience.
