Vacuum lines for the Supercharger bypass valve or for the engine management?
I will tell you right now you best bet is to find a Dyno tuner in Japan (shouldn't be a problem) and get it tuned with a different computer, like a Greddy E-Manage system. If you don't want to do this, then I highly recommend removing the supercharger and just learn to live with normal aspiration.
I am still waiting for a TRD product to please me.
