SUB2 x Bend Calibration S55 Track Calibration

THE END-ALL TRACK CALIBRATION FOR YOUR S55. We've been tracking and developing S55 cars for years, and one thing has always been trouble: the torque curve. The S55 is a TORQUE MONSTER, which makes it a fun ride for the street, and fun for passengers, too. But on a circuit, we want linear, usable power that climbs to redline, and a throttle that can be modulated between 10-90% input. Tall order? Yes, if you're just running Off The Shelf (OTS) tunes, which is why we've teamed up with the motorsport tuning team, Bend Calibration.  We've successfully dialed out the low-end torque spike and have a base calibration unlike any other on the market. This tune alone shaved nearly 2 seconds off at Buttonwillow in our SDC M4 Time Attack build.  FOR OFF-ROAD USE ONLY Here's what you'll need: ECUtek Programming Kit - Bluetooth Programming Dongle + License + Phone flash $865 SUB2 S55 Track Tune - Two maps, Flex Fuel capable - $1200 Bend S55 Fuel Filter Kit - protect your engine and keep your inject
