1.8t questions

hi, i know a person who just got a 2000 or maybe 2002 (im not sure) 1.8t jetta and im skeptical about what theyre telling me. first, he says its bone stock except for intake and exhaust and hes running 14 pounds of boost for 320hp. is this possible? i assumed that the jetta didnt come stock with a boost controller and even if it did theres no way this would be possible on a stock setup. thanks for info
