Default MPG's with 87 economy Tune ?'s

I am curious what everyone is getting with the 87 economy tune...

So - after that, I have a couple questions...

#1: I am getting right around 15 mpg - according to the computer. But when I do the math - it is at least 1 mpg off (sometimes 2) at around and often below 14 mpg.

#2: Maybe it was a pipe dream, but I thought that with this programmer, it would jump to at least 16.5-17.

I have an '06 F-150 (5.4 Triton), and a lot of my miles are highway (which makes me think that the mpg's should be higher). Also, I have a drop in K&N filter, and the Magnaflow SIDO exhaust...

Any thoughts... ideas... comments... would be appreciated (maybe I did something wrong - but I'm pretty sure I didn't )


Thanks everyone!!!
