Who do these folks think they are kidding ? Be careful what you buy on ebay... A Dinan chip for $90? 43 HP for $90? 21 lb/ft of torque for $ 90? A rev limit of 6800 rpm ? Give me a break.. don't get burned guys... I know each mod for my car is thought out in great detail' cuz to be honest I just don't have the money to throw away... Checked with a local BMW Tuner/Dealer www.concordmotorsports.com and they said this add http://cgi.ebay.com/ebaymotors/ws/eB...spagename=WDVW is a joke... you get what you pay for... I'm just wondering if anybody out there has been burned ....
