RLS, I've added an ECIS CAI and Jim C chip to my M Roadster and, though neither has added much to measurable performance, both have subjective benefits...sound, driveability, etc...which have significantly enhanced my driving enjoyment. For my money, these mods are worthwhile and I plan more changes in the future. Try it, you'll like it! LeroyC
: An earlier post made me go back to my current issue of Rondel and read the comments on aftermarket chips. It refers to a study conducted by Road and Track that summarizes some years ago, when the EPA was making our cars run poorly for the sake of emmisions, the chips restored a lot of performance. These days the manufacturers have such good systems that there is little room for improvement (except by raising the rev limiters and top speed). Rondel went on to say that many chassis dyno runs are not very repeatable and one could easily be found to show a benefit one day and an actual loss of performance the next. Since all we get for our $400-500 is a bunch electrons, I am really cooling off on the idea. Has anyone ever run a pair of same-model bimmers side by side to see if a chip really works? It is starting to appear to me that most of these little add-ons (CAI, chips, filters, etc) are of so little value the they are a waste of time and money. I hope someone can change my mind because it is a lot of fun to change everything one can!
