Performance DME chip upgrade improves horsepower, torque, and driving characteristics by reprogramming various sensor inputs, air/fuel ratios, and boost pressure (if applicable).     

Unleash the power of your 993 and discover the grunt and power the Porsche 3.6 motor is capable of. Eliminate the sub 4000 rpm lag, and make your car come alive. Have your engine 'come on the cam' right off the line, with a very significant increase in low and mid range torque and throttle response, vastly increasing everyday drivability and usability. Capable of breaking rear wheel traction with the crack of the throttle, discover low rpm throttle steer from your 993 at your next autocross you never knew your car was capable of! Owners of 94-95 993s have described the change in performance as feeling faster and stronger than a Varioram 993!

Guaranteed to outperform, all chips have a 100% satisfaction guarantee. All programming by default is designed for 91 (95 RON) or higher octane fuel usage. If programming for 93 octane (98 RON) fuel is preferred, please note your octane program preference in option window provided. Also, unlike some other chips, our chips will not trigger your check engine light.                         

NOTE: This is not a physical/shipped product. This upgrade requires you to send us your ECU for re-programming. You will be emailed a download link with detailed instructions after adding this to your cart and checking out.

• DME/ECU upgrades are available for all 993 Carrera models - Early model 993's (1994-1995) typically use a DME software chip, while the later cars (1996-1998) use an ECU software tune.  Cars equipped with the "drive-block" feature (any model years) use an OTP-style ECU.  You can verify that your car requires an OTP by inspecting the stickers on your factory ECU.  

• ECU’s containing 993.618.604.00, 993.618.604.01, 993.618.604.02 are OTP.
