hey... sorry about taking forever to get back to you, I`ve been away for a while..
have you done anything to your plate yet? The procedure I relayed to you is the same that I did for my truck, and it worked out great. I think of it this way, you cant hurt the pump with this mod, and at the worst case, you can always buy another plate.Trust me, once you've done this mod, you will not want to return to stock. As for fuel mileage, nothing really changes unless you put your foot into the pedal a lot. I still get 22mpg on the highway with my #100 plate.
There are no actual specs other than what was posted on the forum.
