First off, I don’t have anything to sell. So all I can tell you is what I have and how it’s worked for me so far. Your question is you want opinions of the Banks packages. I have a 2003 6.0 crew cab, yada yada yada. I use the truck mainly to pull my 36’ fifth wheel camper. I’ve logged about 40,000 miles on the truck and trailer after installing the Banks Big Hoss Package with the six gun PDA and its worked fine. The installation went well, every thing fit properly and the package increased my fuel economy by about 5 mpg on the highway and 2 mpg when pulling my camper. So, I’d say its paid for it self over the years.
I had a Predator tuner prior to the Banks and during a tuner download something went wrong, I couldn’t get the factory or the modified tune to load. I was stuck far away from home. After that I went with the Banks chip set over the tuner. If something goes wrong I can unplug the Banks chip and run OEM Ford. I like how the Banks defuels if the Exhaust temps get too high, I also like the programmable audible alarm points that can be set up to monitor oil, engine temps and so on. The Banks muffler has a deep throaty sound where as others have a load cracking exhaust sound. The Banks package has been very reliable; I haven’t had any problems so far. I keep hearing all this negative Banks talk but it just hasn’t turned out that way for me. But I’m not using my truck as a sled puller or a drag racer.
Good luck
