Selling my slightly used Sprintbooster for BMW automatic or manual transmissions. I am looking for about 235-240 shipped in t he USA. I bought this through the group buy a few months ago and bought it for 250. Let me know because I think without the group buy, it was either 300 or 275. You can post here or pm me. Thanks guys.

I forgot to mention, that I am selling so i can buy other stuff. I have a heavy foot and while the Sprintbooster does make a difference, I would rather buy a CAI or some subwoofers. I currently have a 2007 bmw 530i SMG. Thank you

I've already got one, but are you _sure_ this is for "automatic or manual", as every place I've seen that sells these offers two separate products, one for manual and one for auto. If you buy the wrong one, you get an error/warning ...

+1 That's right different SB models for AUTO vs. MANUAL.

I am positive that it is for the AUTOMATIC! Bump

What does the sprintbooster actually do to the car? I mean, I have a problem with the car lurking forward already. Does this make is lurk more when I tap on the pedal?

What the sprintbooster actually does is tricks the pedal to think its slightly pressed, so that when you finally tap it, it goes instantly, than the normal delay when your press your BMW pedal. (I believe its there to prevent your tires from spinning out or something along those lines.)

When you drive the car, it seems as it is going faster. I mean when you first put it on, you can feel the difference. But after a week or so, I did not notice it that much. I guess I got used to it. I have the SMG and when I am on the freeway and in auto mode, it shifts faster and provides a some what of a smoother downshift. It is a good product, put when in the last 10 to 20 percent of the pedal, you do not feel the car moving faster or the torque increasing. So basically you reach you max throttle output before you actually stomp on the pedal. So if you have a heavy foot, I advise not to invest in this. Its a great product to try, but not worth buying when there are so many other things that you can buy.

Final price is 220 shipped to anywhere in US. Let me know or I will just keep it. Thanks for looking.
