We haven't check the code yet, I'm guessing it was a lean condition when I first started it. As far as Dynoing it, I didn't plan on it. Hurst and Magnuson to leave it with the tune they provided. But see what power it makes, I do have access to a dyno.
Depends on the CAI but we saw something in the order of 30rwhp with rwamser's Cervini setup vs me and Speedy using the stocker air box with K&N drop in filters (this was at ~12psi...dunno about 6 or 8psi) and back to back dyno pulls. Dynos are different the world over, but this is what we saw at Arrington.
Bottom line, the restriction is magnified by the blower so either get creative on opening up the stocker box or rig a CAI to let it breathe more freely.
