Adding the intake and exhaust really woke this truck up. I never really felt the twin turbo 3.5 was all the hype. Now it's like a whole different truck and sounds like a Raptor when you get on it. I never really noticed the boost gauge doing much. Always in the low single digits. Now it bumps to double digits pretty easy. You can tell it's breathing now. Will be interesting to see what a programmer does to it.
Now it should get better mileage if I can keep my foot out of it to make it go brraaapppp.
