looking for the best tuner for my f150 limited with the 5.4. I pull a 22' 4,000lb boat pretty regular and my milage drops from 17 to 8...

 

a gas motor isn't going to see that much improvement. Hypertech is spending a serious amount of money advertising their Economy box, it might be worth a try. I'd suggest Sniper's software, and that's because I love mine. SCT is probably a good choice too.

 

Thanks ReAX
How about cold air intake? I noticed you didn't like your Airaid...

 

I didn't like my airaid poweraid throttle body spacer. I do like my K&N Fipk. Once again though, it's a power adder and not a mileage adder. Any increase in mileage will come from your right foot.

 

Just FYI...

We private label the Edge Evolution for your vehicle -- we call it the Gryphon. The major difference is that we can custom tune the Gryphon to make the most of a customer's modifications or to help with issues like yours. Our customers have reported gains of 2-3 mpg with custom tunes.

Check out our website if you'd like more information.
