Ok, well after a few hours and some solid labor I installed my new Banks Boost tube and Economind tuner. Also while I had the wheel well out I installed the fuel filter access panel and changed the fuel filter. None of it was too hard. I read the manual from front to back and there is nothing really explaining the actual power levels, so I had to call Banks Tech Support and they really didn't offer up much as for specifics but just said "don't tow past level 3." The rest is just "figure out what works best for you." The labor was done yesterday so today I got to drive it. I started in level 2 and worked my way to level 4. A lot of around town driving. I have a 200 mile trip tomorrow so I think I'm going to set it to 5. I don't want to go to six yet because I don't have an EGT guage. Just some easy driving so shouldn't be an issue. We'll see how the mileage turns out.
