Anyone running a positive air shut off on their trucks?
I might be pulling mine off (never used) and selling it.

For those that do run one did you notice a decrease in power once the shut off was installed?

I have one - its a full flow Roda Deaco Valve. Hasn't affected performance at all. I would take it off it you don't need it - especially if its electronic because if you ever get into the heavy grade braking of the alli you could be in for a surprise.
