What does a valet switch do? I've read the sticky and it didn't really explain what it was for. I've done a search and it appears it's supposed to help your mileage somehow, but I'm not sure. Could someone explain it please?

 

I think I understand now. Thanks for the help.

 

It does not let the boost pressure move the fuel pin which in turn doesn't allow for "full fuel. Hope that helps.

 

talking about that ryan did you ever get those parts to put one of them there switches in my truck

 

That would be a negative. To worried about putting a trans in my truck right now.
