I done installed my new return fuel line from the injection pump, cleaned out the gunk in the bottom of the fuel tank and put the fuel tank back in, installed the new fuel canister, and got to another point that I need a part to finish it...ugh...new draw straw is in a position that makes it difficult to hook up to the airdog fuel line without kinking the line, so I need to get a 90° hydraulic fitting to hook it up without it kinking. not exactly a part I can get at a hardware store. 
joy.
once I get that fitting in and installed, I can hook up the airdog return line, put the truck bed back on, put the rear bumper back on, and turn my truck around so I can rack it and install my 08.5+ steering and carli low mount stabilizer

My truck has the speedo gear for a 33" (305/70/16 or 285/75/16) tire, but I have 35's on it. So when I record my mpg, I divide the number by 33, then multiply that number by 35. So to correct for yours, if your speed sensor thinks you have stock tires, divide by whatever the stock tire height is, and then multiply by 33 (I'm assuming you have 285/75/16's).
Hell, everyone else is quoting/reposting this picture. I will too.

Nope, your speedo is driven from the rear wheels speed sensor. (started that trick in 98.) Only way to correct for tire size on yours is PCM reprogramming. Unfortunately, Hemifever tuners do not as yet have that capability. (so far as I know) You can change gears without affecting the speedo though......
Okay, but that's why I said speed sensor for your case. Same theory still works. Google tire size conversion chart and you can find exactly what size your tires are and were. BTW 265 is the width, not height.
