Keep the boost down to about 15psi and you'll have no further problems. If your friend simply MUST crank the boost up to 17-20 psi, he MUST do work to his fuel system.
ok cool. i had a 95 with a big16g and never had a problem at 17psi but i know that some cars act differently than others. ill have him keep it low until he gets supporting mods.
