Sprint Booster for Pontiac - $319.95

"First the good. Literally took me 5 minutes to install and no tools needed. What it does is give instant power when you want it. When you don't want it the throttle is easily feathered. You can really feel the difference at takeoff from a full stop and at cruising speed you'll feel the push to the back of your seat without having to fully stomp the peddle all the way down like you do now."

"Without the SprintBooster the peddle is mushy and you don't really feel the power right away. It's more of a gradual build up. With the SprintBooster the power delivery is almost instant. I was getting 20 psi in boost in a matter of 2 - 3 seconds and could hold it longer all the way through 1st and 2nd gear on a limited stretch of road. Without the SprintBooster it took anywhere from 5 - 8 seconds to get fully up to 20 psi and I would run out of road before being able to get all the way back up to 20 in 2nd gear. So it doesn't give you any more power than you already have. It just lets you tap into that power a whole lot faster." Review from Solsticeforum.com
