Purchase Split Second - Turbo Tuner engine controller, E82 E90 E61

The Turbo Tuner from Split Second is an exciting new product for improving the performance of your 135 335 or 535 BMW.

This small module can net a gain of 40WHP and 50ft/lb safely, efficiently, and reliably from the BMW N54 Turbocharged engine, all while maintaining the smooth driveability and response you have come to appreciate. It's simple layout means that almost anyone can install it, even without mechanical experience.
Its design necessitates no special care from the owner. It has a "soft limit" circuit to ensure that boost is regulated precisely, with no spikes or overboosting from the turbo. It also monitors under-hood temperature to regulate boost pressure accordingly.

Best of all? Your cars computer need not be modified or 'flashed' in anyway. It installs quickly with just one connection, and is removed just as fast so there are no issues if the car is to go in for service.
