i like my new superduty. it's a 6.8 v10 tq shift auto. right now with just under 1k miles the gas mileage sucks...i think im right around 6 mpg. the truck rides great, very quiet, handles well and is all around a nice truck. my biggest gripe other than the gas mileage is the throttle response which is like a bad chinese movie....a second or so delay when i push the pedal down aggressively while moving there is a good delay before it kicks down and goes...rather annoying to say the least. from a stop it doesn't do it but it blows the tires off anyways would some sort of programmer help gas mileage and make the throttle performance or power any better? i am familiar with diablosport and sct (my favorite) for mustangs but do they have that stuff for trucks and are the worth it?

thanks
