I've been off of the list for about 2 years, I bought a 325 iX. A friend has an '89 200. Are any of you aware of an inexpensive turbo mod to increase boost on this model? I read something about it in 1996, but I have since reconfigured my computer at least 3 times and have misplaced the file. Thanks for any help you can provide. Case Biezenbos
