There was absolutely no problem with the installation, I didn't even use the instructions as it's pretty easy to understand the process by looking at the details. (I have a power throttle body) I don't know about mileage increase as I really don't care that the sled is heavy and my driving habits are not conducive to fuel economy. What I was looking for was…
