Mike, I wish I'd have know about your interest in the sprintbooster. While we were at the dragon you could have tried someone's car with one and compared it to yours. That way you'd know if it was worth the $300 to you. I'd have let you drive mine, but I don't think that would be a good comparison - heavily modded SRT compared to a limited.

It's really about personal preference. For example: NeverEnough bought one and hated it, sold it here in the forum shortly afterwards. I have a very similarly modded car to NeverEnough, and I've had a sprintbooster almost as long as I've had the car. I love it.

There's a white paper floating around that will tell you exactly what the sprintbooster does - technically. A lot nay-sayers state that all it does is press the pedal faster for you. The people that have tried it and not liked it referred to it as twitchy. The people that like it say it is more responsive. Take it for what its worth. The result of installing a sprintbooster is the same: a seemingly more responsive throttle and a quicker response from the car. The sprintbooster is about perception and the feel of the throttle.

The long and short of it is that you won't know until you try one. Ask around at the next meet. I'm sure you'll find someone with one willing to let you drive their car.

Try before you buy.
