Well the 2nd gen has a Garrett T-25 Turbo, this turbo will spool to full boost at about 2000 rpm when in excellent condition, it cannot breath much past 5600 rpm the 4G63 redlines at 7000, that is were I got the lack of tope end, not top speed. top speed is not relative to how much PEAK power you have it has alot more to do with peak torque and aerodynamics.
Also, the 2nd gen's stock BOV bleeds of boost over 15psi I believe.
