If its not build i wouldnt push it more than 12psi. 10psi daily driver. I never had a ls but this is what people have told me.I might be wrong.

 

yeah i mean completely stock ls i was thinking about 5-7psi...

 

as good as your tuner is thats how high you can push it

 

I'm not an expert on boosting a stock B series engine but the usual safe numbers are between 6 and 12psi.

You can go up to 12 or 14 psi but don't be surprised if you get a thrown rod or spun bearing. Keep it under 10psi with the proper tuning and your usually ok.

 

ok thnx dude il prolly go under 8 to daily drive once i re-build my SI
