I have seen on many web sites where there are computer chips that remove the speed limits and improve performance. Has anyone done this in here and if so what was the result? What are the pro's and con's of doing this? Any thoughts and feed back would be appreciated. This would be done to my 1994 E420.

Thanks,
Allan
