RENNtech tunes the SL65 Black Series


RENNtech is making progress on one of this year’s most sought-after supercars, the Mercedes-Benz SL65 Black Series. Initial ECU programming results on the twin-turbo V12 were remarkable. And after further testing and development RENNtech massaged 630 HP / 765 LB-FT at the wheels on the in-house dyno. In the case of this particular dyno run that’s 67HP/69LB-FT over stock. Helping to plant that tire-liquifying power to the ground is a custom 100% locking limited-slip differential.


RENNtech will continue to pump up the SL65 Black Series and expects to have even more substantial numbers as R&D progresses. Stay tuned!
