I am wondering which BOV to use on a 99 P1SC 4 PSI LS1. I plan on upping the boost in the future to 5 or 7PSI.

 

stock bov is fine. Im running the stock BOV with the d1 and 12 psi

 

12 psi?

Built motor?

 

shouldn't need one until @ least 10psi

the stock bypass valve that comes with the kit should be sufficient to about 10psi or so
