I've got a tee off of the boost sense line going to my GEMS box. That way I see what the box is seeing (before of the throttle bodies).

^^^^^If you do it that way your sled will always read boost......you should try and tee from a line behind the throttle plates so you get a boost reading of what the lbs the engine is getting.

Always behind the throttle plates.

so can i plumb in the boost gauge in to one of the two lines going/coming from the blow off valve. there is a upper and a lower hose coming off the bov. which one do i use. i cant see which line goes back to the throttle bodies.
