Ok, so I have come up with some interesting info. I started by checking a 2003 6.0 truck we have at work, then checked a buddy's 2004 with a 5.3 and they both showed 100% on the scanner with the pedal floored, however, the pedal floored is stopped by the carpet/rubber floor mat in the trucks. I could get my finger behind the pedal where it would contact the back part (the part that bolts to the firewall) on both of them with the scanner showing 100% throttle. This leads me to believe that it is normal for them to work this way. I had originally thought the TACs were different because on my buddy's car it originally had the adjustable pedal and with that pedal it goes 100% with the pedal touching the back part. Makes sense because the adjustable pedal doesn't hit the floor covering at all. I think the touchieness of his car, and probably others, is due to the fact that the pedal has been cut down to fit better, but what that does is removes some of the leverage the stock pedal has, meaning where as you would have to move the end of the pedal, say 3 inches in stock form to get full travel, when cut way down, it is only 1 1/2 inches now, if that makes sense? Nick, you're still welcome to try my TAC, but I think it's going to be exactly the same, so I would mount the pedal and get the carpet in it and see if the carpet will physically stop the pedal at the half way mark like on the donor trucks.
