Trying to get a little more noise out of the supercharger. Will a 3.1 help with that?

Any tune needed?

You don't need a tune for a pulley per se. But stock injectors are pretty much maxed out from the factory with stock pulley.
So you would need a tune for those.
Honestly if you just want a bit more pep from your daily, a 3.1 pulley and 42# fuel injectors will suffice. Id look into making sure your intercooler pump is working and possibly a dual pass endplate as well for extra assurance

@Dovahkiin Is it a Metco pulley? Beauty of the Metco is you can swap pullies in less than 30 mins once you get it swapped. A 2.85 is safe for 93 with stock injectors.

Is this true?
Can anyone chime in? I see a tune and bigger injectors needed for anything under 3"..

Stock injectors are pretty maxed on stock pulley. I'd recommend buying 80s and calling it good. You could swap pulleys at any point or run e85 if you wanted too

Yes. You'd need to get tuned for any sort of air/fuel mod
