335I ECU Tune is one of the biggest gains that you can do the N54 or N55 335I turbo motor. The E90, E92 335I can be flashed via the OBDII port so you are altering the direct ECU file and can revert back to stock anytime. With this programming you can raise O2 limits, rev limiter, and of course give the car more horsepower and torque. On the newer F30 car, this is done with a ECU Tuning Box. The mult-channel tuning box connects to sensors on the car to control the boost, fuel, and timing giving you up to 60 horsepower over stock. These can easily be removed and installed for warranty purposes. Besides the 335I ECU flash, we also have Power Pedal kits, Auto Flash programmers, and even do diesel cars.
