Ive put a reader on my truck and wide open it reads 74.9 % does anyone know how to make it 100 % ... ive even tried the mod where you push the pedal down and let it up slow.. i dnt know what to do

 

Trying to remember to make sure I've got this right...

it might actually be 100% open. the reader may be expecting a 0-5v signal but the control mechanism could be set that it's 100% open at 4 volts...so your reader would see that as 80% open. havent seen this on a ford site yet but I have seen similar comments on forums for other brands through the years.

 

I tried the mod and it didn't really affect my throttle much, or so it seems. I don't have a tuner yet so I'm not too sure what my actually throttle percentage is.
