My orignial BD Torque Dog apparently lost its program so I exchanged it for a Torque Dog Plus. This one has a 3-position switch and came with a brass fitting I assume to be for the boost system. The instructions list this part in the bill of materials but don't mention it anywhere else. Anyone know where it goes? Thanks. ???

 

I would anticipate it is for trucks that have an aftermarket turbo like the PDR HX40 installed. Those have a pressure fitting on the compressor snail that controls the wastegate, and you install the bleeder elbow to raise the pressure at which the wastegate opens.

 

Sounds like a "boost elbow" that would be used to raise boost pressure on manual trans trucks. That setup would not work for you if you have an auto.

 

Thanks for the replies. Now another question on this: Why can't the boost elbow be used on a truck with an automatic transmission?

 

I believe it is because on the auto it is hard lined. I know on my 6 speed it is a flex line. I don't know why.

 

The elbow will work on your truck. The hardline wastegate didn't get used untill 01.

 

I have an auto and use the boost elbow. Now I can get up to 30# boost.

 

Isn't the boost elbow actually a fooler to keep the computer from seeing the higher boost numbers? I thought that the computer would balk at anything more than 20#'s?

 

The boost elbow hooks to the compressor side of the turbo and bleeds off pressure to the wastegate. A boost fooler hooks to the map sensor & doctors the signal to the computer to trick it in to thinking it has a lower pressure. Most of the performance boxes have the fooler built in, or you can just buy a fooler.

 

Thanks for the replies. With your help I figured it out yesterday and now get up to 30 lbs of boost.
