I have a 2004 Excursion PowerStroke with a 4 in. ProComp suspension lift, bought the truck with the lift on it.I am currently having 315/75/16 Firestone tires with Motometal 951 rims put on it.I need to have the computer upgraded for the tire change.I'm thinking of going with the Superchips programmer,does or has anyone done any re-programing?I'm not looking for a bunch of extra power,this Ex is driven by my wife,just looking for opinions on what works best.Do the milage master programmers take power away or add to it or stay the same,seems like this beast wants to lay-down till the turbo is spooled up from a dead stop.It already had a bigger exhaust and K&N fipk kit on it.
