Hello all
Just wanted to thank you for the suggestions. I had bought an 4.4 X5 new in 2004. It now has 85,000 miles of worryfree driving. It has been a pleasure to drive and a beast of a performer. So I wanted another BMW to transport the family with less miles. I picked up a great deal on a low mileage 2007 530xi cpo. The first weeks driving the car it felt disconnected. I was very disappointed. So I started to search the internet for some advice ect, came across your site. One month later the carbon filter gone, sprint booster installed and I have reset my transmission. The transformation is amazing. Thanks again

Welcome to the forums! The E60's are already amazing cars stock, but I felt the same way when I disovered these forums. Even with a V8, the car felt a little sluggish and bland. Through these forums I discovered that little miracle device called Sprint Booster, deck spoilers, Remus, remaps, and the like. Its a beautiful thing to be individualistic.
