OK guys good job so far...keep the info coming. First of all I know you can't get more HP, Torque and better MPG as there is no free lunch. All three are touted to varying degrees on the product websites and I am just trying to sort/wade through the bull. The ability to tune to the specific usage such as towing vs every day driving has appeal...and of course comes with a price tag. The current truck runs well as did the previous F-150 until it developed a phantom electrical short. I'm always on the look out for improved performance and haven't plopped any money down just yet. I never drive with the heavy foot of youth, in fact I drive this truck more like the old man I'm rapidly becoming. There may be nothing here for me in a $70 "chip" but some of the other systems discussed here sound promising and I will research them further. Thanks again guys! (o;
