Boost bypass
Please clue me in on the boost bypass setup. Does it keep the blower continually engaged, and is that a bad thing over time?

I would just say search, but im gunna go ahead and help ya out.
The waste gate that vents excess air from entering the motor is controlled by vacume. At idle, the vacume is high with in the vacume system. So you put more and more load on the motor there is less and less vacume in the system. The waste gate is open at high vacume and closed at low or no vacume. But there is what is called the boost bypass solinoid. This is a solinoid that is controlled by the PCM (computer) and is tripped when it the PCM decides to go into limp mode. This generally occurs when you hit the rev-limiter comming out of a burn out. So JDM makes a elbow kit that will take the boost bypass solinoid out of the vacume system, thus leaveing the computer unable to controll the waist gate. But rather than spend $25 on the kit, you can spend thirty seconds and unplug the solinoid from the computer.
To find where the solinoid is to unplug it, you'll have to search. Maybe someone will post a picture for you.

just spent five minutes digging through the archives to find this:
Disconnect the connector in the blue rectangle. Make sure it is the right one. Also, just so you know, there will be a soft code stored in the PCM when you disconnect it. But it is easilly cleared by diconnecting the battery.
