Started on the rats nest, not as exciting as a supercharger but currently have 2 4/0 power runs, 2 4/0 grounds. 5 runs of 12 ga for the front doors and rcas ran. Need to order another 100ft of 12 ga to finish the driver door then start the rear.

Cleaned up the floor liners these things sure have saved the carpet from puke, spilled soda, coffee, mud, candy you name it, not as exciting as putting in a supercharger though

Got my Esky appliques installed. Not as exciting as a supercharger. But it cleans up the rear body lines nicely.

Yeah, pretty much everything posted in this thread from here on won't be as exciting as a supercharger.

I have just returned from a road trip that stretched from NYC to Salem, Massachusetts. The truck performed very well on the highway during the 5+ hours of travel but I wish I could say the same for the gas mileage. I had a maximum of 450+ miles on a full tank but my average mpg stayed at 14.1 the entire trip. If there’s anything I can do to help increase the fuel mileage that would be great. I recently put in a new engine air filter and maybe every 3,500 miles I treat the fuel system with Techron

Just curious, did you reset the dic at fill up? What kind of speeds were you doing?

Does it have a supercharger ?

accelerate like a 90 year granny and keep it at 55 that's about the only thing that will garner you more mpg
