Porsche 955 Turbo EVOMSit ECU Tune

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

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.

SHIPPING DETAILS: Shipping costs for sending an ECU to Fabspeed is the responsibility of the purchaser.  The ECU will be tuned within 24-48 hours of receiving it and Fabspeed will then ship back the ECU using whatever method it was shipped in with.  (For example: If you send in your ECU via Ground shipping, we will ship it back via Ground.  If you ship it via Overnight, we will ship it back via Overnight.)
