wich boost gauge would I need 0-35 or 0-60? I'm planning an getting the bully dog torque dog box and an AFE stage I with the torque tube.

 

You are always better off getting the bigger one
That way if you really start to BOMB the truck you have the headroom without having to get another gauge
Besides with the 0-60 max Boost will be about center this way if youever see the needle get to about midway then you know youare overboosting
