Here's what I know - which, admittedly, isn't much -

The Crossfire is a 'drive by wire' throttle, meaning when you press the pedal, it is sending a signal to the TPS sensor and throttle telling it how much to open.

Well, even if you slam the pedal down, it 'gradually' sends this signal until it reaches full throttle. This is a big complaint on 99% of 'drive by wire' pedals (especially with the crossfire), as opposed to those with an actual mechanical linkage, bet it by cable, rod, etc. It makes the car appear to have a lot of throttle lag.

With the sprint booster, this process is made shorter - therefore, you get seemingly better throttle response. It fools the system and speeds up the time it takes to achieve full throttle.

You can say that you drive your car hard, you reset your throttle frequently, etc...but theoretically, this will still help.

It is the same amount of horsepower, same amount of torque, etc.

The only thing that MAY change is the 1/4 mile because you are on the throttle quicker. This could both help and hurt though. If you are getting more throttle response, you'll be more prone to break the rear loose and lose time.
You should also feel like you have a much quicker car when just driving around town.

I bought one used- and I'm not scared to say when I feel like I wasted money, so you can expect an honest review from me. I also drive my car hard, and reset the throttle just about every time I drive it. So, we'll see what happens.

Should have it installed by Friday night, just in time for a good cruise and show/shine.

Report back then and expect a review.
