Okay, I have heard about this a few times. What does it mean, how do you do it and what are the advantages? Anderson has a TB with adjustable TPS screws and they state that "you don't have to slot the TPS" So I need a learning experience here.

My best guess would mean that you can slightly elongate the holes so that you can rotate it a bit to adjust it.

I had to do this on my 5.0. Small file and some effort and it was done. I was able to better adjust my TPS after.

But why would we want to adjust the TPS. Does change the idle RPM's and WOT settings? I am confused, hopefully somebody is out there with info,

Speaking from old school experience , alot of guys used to do this on the older 5.0s , especially guys running the stock classes where they could do any aftermarket ignitions , intakes , heads , cams and stuff , you could make the holes that bolted it down bigger so you could rotate the sensor , which allowed you to adjust the voltage from the factory WOT setting from something like .907 , up to like .998 volts , which tricked the computer into thinking that it needed more fuel , so it would pump more fuel through the injectors , worked pretty good , but not a big SOTP difference , but when you are fighting for timeslips it can make a difference . Not sure about those voltage settings i mentioned , got it wrote down somewhere . I havent heard of anybody messing with it on the 4.6L .
