No, that's not it at all... Even though the boost may go down, you're still gaining HP because your over all flow is going up. Boost is only airflow vs. restriction... Lower the restriction, boost goes down, but air flow can go up = HP goes up. Want more boost after removing a restriction, such as exhaust? Spin the SC faster to bring up the pressure ahead of the engine again. That's why Vortech gives you the smaller pulley to start with on a stock car, then sells you the smaller ones to bring the boost back up once the rest of the car is modded. Find the smaller pullies on Ebay for $20 or so...
