Hey guy I am new to the forum but am enjoying it already! I live in the tampa area going to school but live in manatee county. I was curious if ya'll ever have get togethers around the state or if their is one coming up?

Secondly, I need some advice about my 2000 7.3. I have had it for 3 years now and have never gotten better than 13 mpg no matter what I do! I Have recently downloaded superchips new xs fuel saving file and it deffinatly bumped me up to 13.5 but that is empty on the interstate! generally around town I get 12.5 and when I haul my 6000lb. boat or horse trailer it is 10-11.

I rutienly run lucas injector cleaner through it after every oil change at 5000 miles. granted i have 35" and 3.73 gears but when even before that the milage wasnt much better.

If someone has any suggestions about this situation it will be much appertiated!

When you are cruzin down the interstate what is your speed and how many rpm are you turning? I am surprised that your mileage is so poor

At 2000 rmp it is 73 mph dead on. my speedometer is correct because I have my tires programmed with my Superchip
