Advice needed on '07 5.4

[tmyarb]

Thanks for the info guys! I was able to cancel the intake order before it shipped, and I installed the Gott mod yesterday.

I'm under no illusions about expected gains in MPG. I drive with an easy foot as it is (most of the time anyway); and get 13.5- 14 mpg. If I could squeeze just an extra 5% out of that, it would be 14.7 mpg and a savings of ~$200/ yr.; enough to pay for a tuner in a couple of years. If I could get 16, it is paid for in under a year and it's all gravy after that.

Thanks again for the experienced opinion. Ya'll saved me $300.

I keep saying I saw an increase in gas mileage with a programmer. My non-towing MPG average is 15.2, and I have a truck that is probably heavier than yours with the 4WD and a bed cap (that's slightly higher than the cab, so there's more air resistance too). I know there are no guarantees, but I think Bill's tunes make more efficient use of the fuel.

PHP is offering the older Gryphon for $369 now and tunes are $30 each. You can buy 1, 2 or 3 tunes, depending on your needs. If you don't tow, I'd recommend an 87 octane performance tune optimized for your driving style.
