Hey! I'm looking for resources regarding the 5.4L. I have a customer who is the proud owner of a 2000 F150 4x4 equipped with the 5.4L. He wants to improve performance. We're not concerned with "ETs"...looking to change the driving characteristics of the truck or "feel". I'm researching Hypertech's Power Programmer and have also considered a trans modification...Ford Motorsports doesn't seem to offer a whole lot in the way of mods so I thought I'd ask the world what they think. Tell me what you guys are doing to go fast!
