This upgrade requires you to send us your ECU for re-programming. NOTE:This is not a physical/shipped product.

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

Eliminate the sub 4000 rpm lag, and make your car come alive. Unleash the power of your 993 and discover the grunt and power the Porsche 3.6 motor is capable of. Performance DME chip upgrade improves horsepower, torque, and driving characteristics by reprogramming various sensor inputs, air/fuel ratios, and boost pressure (if applicable).
