Best mod yet
Of all the modifications I have made for my truck, this one made by far the biggest difference to power and gas mileage. Feels like a different truck now. Make sure you get a custom tune from a reputable tuner to really make this stand out. I paid someone to install this for me so can't really give feedback for how hard it was. I've read that taking the old one out is the hardest part.
