It's interesting how the only people who have bad things to say about SB (or are dubious about it) are people who have never even tried it.....while the people who have tried it on multiple cars wouldn't live without it. As a matter of fact those of us in this thread that have used the Sprint Booster before (me and sirees01) are so satisfied with it that we want one for our other cars too.

Placebo effect? Well, that wouldn't explain how my wife noticed that her car felt quicker when she didn't even know I had installed anything on it.

I respect everyone's opinions here and feel that it's great for anyone who is curious about the SB to read opinions from both sides. However, I do have to say that every one of the arguments that you guys are making I have read over and over again by others on other BMW boards (heck, I even made the same arguments myself for the longest time)........but when the same people (including me) finally gave in and tried the Sprint Booster we never looked back.

This is not an "Ad/Promo for this gizmo" and I'm not getting a "cut" from every Sprint Booster that is sold.......I'm just someone with first hand experience with using it on two cars and when the subject came up I just expressed my opinion on it. At $250 (or even $300) it's the cheapest way I know of to add some zip to the car and it can be installed or removed by the owner in less than 5 minutes......which is not the case with most other products like re-mapping, etc.

If you don't believe that the Sprint Booster works, think that it's the placebo effect, or you don't feel comfortable using it on such an expensive car then just remember that no one is forcing you to buy one..............just as no one is forcing anyone to continuously come back and read this "Ad/Promo".
