GMPP offers a really nice clutch upgrade for us it can be found here Home Page
Redlines come stock, idk if a stage 1 is sold anymore you need stage 2 or 3 to see some significant gains.
If it has a boost gauge and you can tell us what boost is wide open we will know if it has a different pulley than stock. Pictures of engine bay will also help.
Welcome to the site, happy moddding!
