Improve your cars' performance yourself with this ECU Software Upgrade for the 1995-1998 Porsche 993 Turbo / Turbo S. 

This software upgrade will improve horsepower, torque, and other characteristics through reprogramming, such as air/fuel ratios, boost pressures, and sensor inputs. There are three options to choose from: 1995 Euro EProm, 1997-1998 ECU Software, and 1996-1997E OTP Flash.

Note: ECU upgrades are available for all 993 Turbo models, but you must specify which style of ECU your vehicle requires. Early model 993 Turbo (1995) use an ECU EProm Flash, while the later cars equipped with the "drive-block" feature (1996-1997.5) use an OTP-style ECU.  You can verify that your car requires an OTP by inspecting the stickers on your factory ECU. Late model 993 Turbo (1997-1998) use a regular ECU flashing procedure.
