Fixing Throttle Response
More guys than not, would say it made an improvement.
Honestly, I didn't notice a difference.
I actually had forgotten all about it. I'm going to, just for the hell of it... give the 5.0 a test.

A custom tune can fix the throttle response permanently, or at least until you change the tune or go back to stock. That ignition trick is likely just a TPS relearn procedure and chances are you are not really getting anything from it.

That's all I wanted to do it for, "The Hell Of It". Doesn't really matter to me, just curious.

no, there is definitely something like that floating around...
placebo effect or not, I dont know... I did it once (I think I did it right) and noticed nothing.
Found this:
"Turn the key to the on position but DON'T start the engine. Now press the gas peddle to the floor SLOWLY and let it come up/back as fast as you can, turn key to the off position. Now do this two more times."
https://www.f150forum.com/f4/throttle...s-5-4-a-71539/
Here is another method as well
"I got mine to 108%. Wide open throttle started being displayed at around 89% and I still had throttle left. On the floor, the pid reads 108%.
I took the assembly out to try the mustang mod, saw that it's a different system on the F150, so had to put it back in after doing nothing. But when I went to reinstall, I saw that the 2 bottom mounting holes are oblonged just a little. I put in the top bolt, and I held the the bottom of the pedal assembly as far forward as possible,and tightened the bottom bolts. turned the key on, waited for the lights and did the reset. Like I said it went from a top reading of 87% to 108%, and the difference from a dead stop take off now is amazing."

The throttle calibration definitely works, as stated though after a week or so it needs it again, especially if driving the truck conservatively. I also took care of the issue permanently with a tune though.

Well, I just tried it. I did the ignition "on", slow depress and quick release of gas pedal. Did it 4 times. Started vehicle and pulled out of parking lot from work. Touched the gas and chirped the rears pretty good.
Not sure if its in my mind or not, but I "think" there is some merit in this theory.
Anway, going on a long drive tomorrow. I guess I will se if passing others is any better (quicker).
Will keep you all posted after my trek tomorrow.
