AA stage 2 upgrade questions...

I currently have stage 1 sc kit installed and have had no issues whatsoever with the car. My next move is meth injection and the switch to 100 octane gas. I want the stage 2 upgrade with the smaller pulley and intercooler but I have a couple questions. Will this require a new tune or will meth plus 100 octane keep it running correctly without a tune? Also, with 100 octane and meth installed do I really need the intercooler or could I just get the pulley and belt?
