I agree. I'm not saying that your product is crap and no one should buy it. I just feel like there is a bit of smoke and mirrors. You say that we have no idea how it "really works" and that your product reduces the lag time. Are we supposed to believe that you got this in the same place Jack got his beanstalk beans from?

I think I would be accurate to say, in Layman's terms, that the Sprint Booster tells your ECU that you are pushing your gas pedal 30% further down than you truly are. Which would also explain a loss in MPG, because your cars engine is behaving more aggressively.

The bottom line is: For someone who wants good throttle response without the need of much accelerator pedal travel, this product is great for you.

Well, I think it's closer to 33%, but yeah, you and I agree 100% - further, since most people spend most of their time somewhere other than at the floor, it's noticeable!

OK. This happens every time someone mentions the Sprintbooster. Here comes the "White Paper".
Here's my thoughts:
I enjoy driving my car more with my Sprintbooster installed. I don't like driving my car without the Sprintbooster.
If YOU don't like the Sprintbooster or even the theory of how the Sprintbooster operates- then don't buy one.
Plain and simple.

Wow - I think I agree?! I don't remember ever saying not to buy one, and I'm happy you love your car more with it installed - I'd hate to think you spent the $300 and were unhappy!

Its the common thing on modifying car... I like CF interior, other likes chrome, some other likes wood/oak trim. Some like to drive with Sprintbooster on, others don't. No need to try to be a smart a**e trying to proof that a product is useless. Hey, some people spend $600-700 just to get original CF interior which doesnt do anything, why not spending $300 for a product that do something?

Well the decision is on the hand of each car owner...
