Im still on stock twins, Greddy Profecb spec II 15 psi, stock y pipe and downpipe, 4" mid to 3inch duals, walbro 255lph running on AEM EMS and the last dyno trip was 387/382.
What's the most boost stocks twins can hadle? I read in a few places that anything over 14psi is a ticking time bomb, but I have also seen many 1jz owners boost way past that, so any real world experience?
