So is it safe on the TRD tune to get a couple more PSI out of the supercharger with a smaller pulley ? Does the mass air compensate for more air coming in? I've seen some run different sized pulleys on the accessories or on the blower itself.

Ran the ASP supercharger pulley for 1 year/20,000 miles with no issues. Power gain is about 30 to 40 HP or 0.25 seconds in a 1/4 mile.
