I was looking to get a new pulley for my SC, would it require me getting a new tune from the ground up or is it something that a competent tuner could tweak rather quickly? Im pretty kindergarten when it comes to tuning.

 

If you're just upping the boost without making other major changes like the fuel setup then it's just a matter of tuning for more boost...same as upping the boost with a boost controller for turbo.
