Had the Eat chip installed about 3 days ago, what a difference it made. I have a 95 540i automatic, I can tell the difference at the low end lots of power. From 0-60mph you can get there at no time, from 60-90mph you can really feel the power, from 90- on wow. Great investment for all V-8 owners or BMW owners. Mark is a great person to deal with, was very nice and professional each time I called him about the product. Get the Chip you will not be dissapointed!
