Also with the tuner you could make an even stronger performance shift mode.

exactly, another good point

and its the CLEAR connector (C2) of the PCM

^^^ That is the initial plan

Beat you all to that suggestion a while ago.

the other thing to keep in mind is the 00+ crowd can add a switch. TommyGloves proved it out and confirmed the ability to add it.

Same with Riviera.

Are these shift buttons on the console? I have the column shifter but would like to add a shift kit to complement the new motor. I would like the ability to switch from normal to a fairly aggressive mode. Or should I wait until I get a PCM?

The 95 pcm may not support this type of change and is also OBD1.5. The pre 96'* are much tougher to tune as you have to get custom Eproms burned instead of being able to program your pcm on the fly with a tuner.
