i can tell you its the best performance mod i have done you can really feel it in the seat of you pants it has 3 setting via push switch you can mount on your dash 1 stock 2 street and 3 almost race you combine it with e85 gas and it really burns up the road money well spent

Not sure how I feel about this "mod" It basically modifies the accelerator position sensor to send out a higher position than what is actually being applied. In one hand it sounds like snake oil and could see why it would fool some people. Your foot is telling you are at 20% throttle but the truck is accelerating as if its under 50%, so in that sense it does make the truck seem quicker. But as far as performance gains 0-60 times will be the same as well as 1/4 mile times.

HOWEVER, the 2014 5.3's do have a knack for having bad throttle position programming. I personally have that complaint, I constantly need to apply more throttle than I should when I want to pass a vehicle in the highway or street. I would really like to drive a vehicle with this and test it out myself.

my sprint booster has been great would buy again just try it 30 day money back what have you got to lose

Just ordered one. My only complaint about this truck is the throttle response. I was worried about a full blown tune due to all the warranty questions.

Will report back once installed....

I finally got this installed. The process is truly plug-n-play. You simply release the plug lock on the wire going to the accelerator, disconnect the plug, plug the Sprint Booster into the accelerator connector, plug the wire removed from the accelerator into the Sprint Booster. Plug the provided push button into the Booster, and optionally secure it someplace in the truck. I secured it to the bottom of the dashboard near my right knee. They provide a small piece of double sided tape. As it turns out, you can use the button to select the mode, then disconnect the button if you want. The Booster will remember the setting.

I have adjustable peddles in my truck and in the full forward position, the OEM wire to the accelerator was too short. The device is about 1-1/2 inches in length. I had to cut the wire wrap to provide more slack in the harness. I secured the wire with another wire wrap.

I've driven about 500 miles since the install. These are my findings:

There is a definite improvement in throttle response in either of the non-stock modes. The less aggressive mode (green light on the switch) is perfect for my needs.
The truck spends less time in V4 mode.
Gas mileage is down about 1/4 - 1/2 mile per gallon depending on highway or local driving.
The perceived lag in highway passing is gone.

Overall I'm really happy with the Sprint Booster. To me it was important to improve throttle response without risking the warranty. I know $300 is a lot of money, but for me it is worth it.

Maybe now, when I drive my wife's 2013 Ford Escape, I won't pound her head into the headrest while accelerating!

I didn't take any pictures of the install as it was 12 degrees in the garage.... Too damn cold!
