I recently was browsing Watterauer's website for chips. I noticed that they have a for the OBDII cars, yes a chip, not a reprogram. They claim to gain to get a 13HP gain and 27torque gain!!. Thats alot especially for the 96+ M3's, from what I hear Jim conforti's shark sucks and actually loses power. They have this "alpha" chip technology where you can simply plug the the aftermarket chip in and replace with stock at any time. Its kinda like shark but with real chips. There is a larger price tag but its actually worth it. Its $700 for the whole kit. I just thought yall might want to look at it. they even have pictures of the chips and the chip module. just click on the link below, then go to products, then bmw chips, then 3.2 liter US M3.
