I did a couple of searchs and found nothing. I was just wondering if anyone has heard anything about this product. Do you really think it works and really how actuate is it. I saw it in this and last months issue of Super Street. Theres an ad on like the third page of this month's issue. Check out the website and let me know what you think. Sorry if this is a repost, but like I said I did a search and found nada.
