2000 saleen with kb 14psi

[Saleen s281]

just got back from jdm and with 12 psi my car made 410 rwhp and 405 rwtq. then switched to 14 psi and made 455rwhp and 474 rwtq but at high rpms the belt started to slip and my boost droped 4psi.going to order a shorter belt and go back to jdm to get it retuned. hope to hit 500
