Map line and boost gauge placement
I'm thinking of drilling and tapping my intake for the boost gauge. I've seen a couple folks have there map and boost gauge lines on the hot side (???) of the spyder (?) just after the turbo. I've read that you see boost sooner at this point. Is there any benefit to this?

Tapping the MAP sensor on the hot side helps with off the line acceleration, because the MAP sensor see's the boost sooner, which tells the PCM to add fuel sooner, and this speeds up the process of spooling up the turbo!

Forgive my ignorance but I'm learning, don't these trucks already have a MAP sensor? If so, are you saying to move it to the hot side?

Do you have a pic of this, I don't want to screw it up. It's probably real simple I just need to be sure.
