Why was it bypassed in the first place? What is the history on the vehicle?

That valve controls the out-flow of the air pump.

Hook it up, hoses and all, just like your friends car.

Or buy a real bypass kit (designed for and works perfectly on US spec cars) from me and get rid of all the airpump crap.

to be honest idk why it was by passed but the car felt a lil faster after we did it but driving home like 3 out of 10 times that i poped vtec it actualy pulled. today after school it ran a lil better and poped vtec more so idk ima jus see what happens and how the car reacts for a little

Ok, well the seconday air pump has nothing to do with vtec, just extra weight slowing you down. Even if hoses were routed incorrectly, it would just show a CEL, not put it into limp mode.
