need a new apps i believe.
 

my truck when it is in over drive it jerks when i get on it, mainly when the boost start coming up. i origonaly thought it might be overboosting and dufueling. so i got a power puck with a built in boost fooler. hooked it up yesterday, and it was pretty much un driveable. it would buck and cut out so bad anytime it i tried to accelerate. if i got it out of the throttle right away it will die on me. i had to pull it off. i was told to check the apps cause it might possible be that. well i checked it. it is putting out .510 and it calls for .633. so i tried to adjust it, the highest i could get it to adjust to was .580. it did make a little bit of difference but still doing it. do i need to get a new one to fix the problem? it wont be right away because i dont have the $550 the dealer wants for one. what do yall think.

thanks Eddie

You don't need to pay dealership prices for an APPS, there is a guy offering an aftermarket APPS for a fraction of the cost, I have one and have been happy with it. You can find the info here:
Alternate APPS

to me it looks like a resistor... lol i dont know what an apps is...

Sadly enough, that's pretty much all it is: a glorified resistor... :humm:

wow and they want $500 for it??? go to a new holland dealer and buy a resistor off a nh baler they are 50 bucks and looks almost the same lol

It is a over glorified resistor with 2 switches in side that why the alternate APPS was designed by a guy named Timbo...

it might no tbe reading right but its fixed now. hooked a hiper tech up to it and cleared the codes and now she runs like a top.

:humm:

:humm:

Thats like mine every once in a while. Got the dead pedal like that last month and happened before in July. It kinda comes and goes but the APPS is gonna need to be replaced.
