As far as I can tell, it does what it's meant to. I put this on before I put on my Spectre cold air intake to test it and noticed an immediate throttle difference, definitely added some power. And it hasn't messed with my mass air flow sensor. Don't buy this to save gas though, I haven't noticed much of a difference. Wasn't too hard to install either, just make sure you have a socket set and a pair of vice grips at least and you'll be fine.

ALL MATERIALS PROMEST WAS IN THE BOX. AFTER INSTALLING THIS UNIRUCKT I TOOK THE TRUCK OUT FOR A DRIVE, IT SEEMED TO RESPOND TO THE THROTTLE QUICKER. AFTER DRIVING THE TRUCK FOR A WEEK, I NOTICED THAT ONCE I SET THE CRUSE CONTROL IT DID NOT DROP SPEED WHEN GOING UP HILL, THAT SURPRISED ME. DRIVING IN MY NORMAL WAY THE GAS MILIAGE CAME UP TO 15.96 FROM 12.96 THIS IS A GREAT THING FOR THIS TRUCK. WHEN I UNPACKED THE DEVICE OUT OUT OF THE BOX I NOTED IT HAD TWO NICKS IN THE SPORAL PART OF THE UNI

So first of all let me start by saying this thing does have a whistle noise even though it says its quiet. I do have a aftermarket intake and I'm not sure whether it makes it whistle more because of all the air coming in faster. Also I had to cut some plastic to make it fit because of aftermarket intake. Now for the mpg/hp/tq gains as far as the mpg I'm not too sure on that but I do have better throttle response and my truck gets going better than usual my truck does feel like it has more power.
