If you think it's easy to lose control now, you'll really enjoy how much easier it is when you toss on a PD blower kit. The Roush and Whipple both use a bypass system which keeps the engine completely out of boost under light throttle. When you hit the gas a gate slams instantly shut and you are at full boost. Like flicking a light switch.
My car goes from -12 inches of vacuum at cruise to 9 psi of boost in a blink. No gentle transition like, say, a centri blower. Instant massive increase in torque/power. Not linear like you are experiencing now. It takes some getting used to. But you do. I hardly notice anymore when I'm half sideways.
You will love it.
