1995 powerstroke problem with #4 position on bullydog 6 position chip

[muckin's truckin]

I have a 95 powerstroke with manual transmission.It has a bullydog 6-position chip. Position #4 (80 hp " highest level ") does not work. I was told it could be a fuel supply issue. Could anyone help? Thanks

What exactly do you mean by "doesn't work"?

Explain a little more please


Thanks

Position 1 is stock, position 2 is 30hp, position 3 is 50hp, position 4 is 80hp, position 5 is carb (meets california emitions) Position 6 is high idle. When you go from pos. 1 to pos. 2 you can feel it, and when you go from 2 to 3 you can feel an increase in fuel (black smoke). When you go from 3 to 4 you feel the truck slow down and the smoke goes away. I was wondering if it could be a problem with the fuel lift pump not supplying enough fuel to support position number 4. Thank you

No, not a supply problem as it is a mechanical pump so no computer telling it to push more fuel. I would think it is a chip problem as it has enough fuel to make power and smoke in position 3 so I would think it would perform at least that well. This leads me to maybe the switch is bad so the pcm doesn't recognize position 4 Since all other postions and calibrations seem to function normally.

And welcome to the ORG.

Agreed.

Sounds like position 4 is either blank, or something is wrong with the switch, and it reverts the truck back to stock in that setting.

Check your wires

I had the same chip on my 96 & at first # 1- stock, truck wouldn't even start, & # 4 it would fall on it's face at wot. I have sent it to PHP to have their tunes installed, can't wait to get it back. No more bullydog for me !!!

Crap chip to start, no tune will get you more than 50+- HP with stock Inj's..Get it reburned if possible by TW or Cale.
