4b12 safe boost?
 

im wondering whats a non dangerous boost for the 4b12 stock internals , im running 7 psi (ran 20 psi for like a block awesome, lmao) but i would like to run at least 10 , we where runing 10 and it felt ok , but my boost controller was cheap and inacurate so we decided to use the wastegate instead , anyways if u got news share please thx {thumbup}
