Achieve maximum power gains (~66 whp & 43 ft-lbs) without sacrificing drivability or reliability. Maps are available for completely stock cars, or for cars equipped with Sport Cats, Cat Bypass Pipes, upgraded turbos, and more.
Fabspeed set out to extract maximum possible gains out of the McLaren 675LT while keeping the operating parameters safely within the confines of reliability and longevity. Once we receive your ECU, our tuner bench flashes it with the upgraded ECU map and we return it to you for easy re-installation; no modifications to the vehicle are necessary.

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.)
