Attention: TDR Forum Junkies Does anyone know why I can't get an engine brake for my 04. 5 truck with a 6 speed transmission? I was told by my local dealer they can not do it. I was going to have one put on by a friend who works at a private shop and he said it couldn't be done yet 
.
I am also disapointed with the milage. I had it flashed last week and don't know what it did yet. I miss my 96 that got 20 - 24 mpg consistantly emp ty.
