I had my truck on the dyno saturdy and we also put auto tap on it at the time. Auto tap is reading my throttle at 16% open with the truck off and only goes to 91% open when floored. I am going right now to check my TPS voltage but am curious how it would be high when closed and low when open?
Oh and i Dynoed 381hp/475ft/lb

 

Weird ?

Do you have an Accu-Fab or other Single Blade Throttle Body ?
Sometimes you have to take the switch off and actually drill it a hair to give it some more adjustment (or to adjust it to where it belongs) Been there, done that.........



BTW,
you must have cake while doing it too, hehehehehehe.................


I'm sure you know how to adjust it BDAZSVT, but for those
that don't, this crappy pic I took when I did mine may help.



BTW
Nice numbers, very close to the 400/500 club

 

No I'm stock. I checked the TPS .98v

 

Well then your fine as I see (.98)

I was always told ONLY AFTERMARKET throttle Body's need to be checked or adjusted ???

So what the hell is your prob ? have you asked a tuner ???

 

Nice lil class on the TPS Rob!!! Thanks! Artie

 

Yeah, Thanks! Pass me some cake. These breakfast burrito's are
hot this morning.

 

I think that those TPS numbers are right ....

Try searching here for an old post on throttle % ... It was confirmed by a tech that the swing is not from 0-100% ...

Okay I will search thanks Silver_2000
EDIT Silver is correct!!
