if you change the MAF to anything other than stock you will need to have a chip, and pretty much same goes for the TB. The computer is set to work with stock equipment, and it won't run properly if you don't have a chip burned to change those parameters to what you install. You'd also have to consider a new cold air induction. As far as size goes, it's up to you, but you'd probably have to go with bigger injectors, and fuel pump as well, and consider a descent exhaust system. To be honest, I'm not sure what a 2.7 pulley is, normally we use either a 5 or 10%

common sense...
so rare,
it's kind of like
a super power

It simply depends on your anticipated power level. As was said you'll need a chip to avoid problems with the load calculation done by the pcm.

You don’t need a chip to run an aftermarket TB on an SC.
