Among many interesting results, one stands out to me:

Stock - 200-207 awhp (at 23% drivetrain loss that's about 259-268 bhp, which is well above rated 240hp)

 

Performance chips for the R32

*      APR (Serially programmed. Up to 4 programs can be loaded at once and switched between via cruise control buttons)

*      GIAC (Serially programmed. Several programs can be loaded at once, and switched via laptop, or handheld interface that plugs into OBDII port)

*      AmD (see claimed gains above)

*      Neuspeed (modest gains, but inexpensive)

*      Wetterauer

*      EIP 8-9hp and 8-14 ft/lbs torque.

*      Revo - claimed 10-12 hp and 10-15 lbs of torque
