Stock LS3 boost limit? best pulley for Magnuson?

Threads like this make turbo kits seem so nice. Bolt on, make 600-700rwhp, no tensioners, pulleys, 8 rib upgrades, headers, cams, etc to mess with.

Shouldn't slip with a 3.6, but the 8 rib will eliminate any slip whatsoever. Contact Joe @ LeftCoast'32 (760-522-8669) to inquire about the 8 rib setup. the only way to tell if you need to upgrade injectors would be to ask your tuner or take a data log and see your injector duty cycle. Id safe if youre over 105% its time to upgrade.

As long as your tuner says it stays safe, I would go for it. When he/she gets it on the dyno it will be easy to tell how far to push it. I ran @ 7.5 #'s for a while and didn't have any issues.

I dropped to the 3.6" pulley (w/OD cogs) when I added the FPCM and never missed a step.

Totally understand what you are saying but not everybody wants turbos.
