McLaren 650S ECU Tune

Achieve maximum power gains without sacrificing driveability or reliability. Maps are available for completely stock cars, or for cars equipped with Sport Cats, Cat Bypass Pipes, X-Pipe Exhausts, upgraded turbos, and more.

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.      

POWER GAINS

• Gains of 45 WHP and 60 ft-lbs WTQ (Stage 1)
• Gains of 80 WHP and 100 ft-lbs WTQ (Stage 2 with Catless Downpipes)

 NOTES

• 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.
• You must fill out and include a copy of the ECU Information form along with your ECU upon sending it in. Please contact us if you need to send the form in any other manner.
• 1K Motorsports saves your stock/factory ECU settings so that you can revert your vehicle back to stock settings at any time.
