It depends on the car, I think.  A lot of the modern Japanese cars they're
selling these things for actually will compensate automatically if you
have a good oxygen sensor -- the ECU has enough range in its fuel trim to
supply the extra fuel when it sees it's running lean.  I imagine you'd
have to be careful, though, seems like you could break things in a hurry
if the O2 sensor ever failed.
