The biggest increase I see is quicker throtte response. I feel the increase in acceleration, but my tires do not break loose like many of you guys have experienced. At 80 my rpm used to be at around 2700, and how it is at 3100. All in all, this is a mod that was worth it.

Did you change it your self? I am thinking about doing the mod to my wife's coupe? How long did it take you?

Do you have a manual, because at 80 your RPM's should 4250...even the stock 3.15 would be 3500. :dunno

How do you like the transmission software? My 3.91lsd goes in tomorrow, and I get my car back this coming weekend. I hope it is as good as I think it will be.

95 M3's are lucky b/c both stage 1 and stage 2 are in one chip for only $250. I bought it and got 3.91 and the car was perfectly. i honestly still wish i had it at times.
