Split Second's NEW Turbo Tuner 2 is a enhanced version of the original Turbo Tuner plug-and-play solution that significantly enhances the performance of your 135/335/535 turbo Bimmer. Typical gains are 40 horsepower and 50 ft-lbs of torque*. In response to customer feedback, the Turbo Tuner 2 adds several unique features. One is a user-accessible adjustment that allows the user to fine-tune the additional boost the Turbo Tuner provides. The other is a wire harness extension that allows the product to be installed in a location that is easily accessed by the user. Furthermore, the connectors have been improved for additional strain relief. This assures trouble free operation over many cycles of installation and removal. The Turbo Tuner 2, like its predecessor, can be installed or uninstalled in seconds. It does not cause any trouble codes and its operation does not leave any trace that it was ever there**. The Turbo Tuner 2 is not an ECU re-flash solution. It is an embedded control solution that works seamlessly with the stock ECU. The turbo tuner provides real performance gains while it preserves the smooth and refined character of the car.

Returning back to your Bimmer's original settings is as easy as unplugging the Turbo Tuner from the TMAP (Temperature and Manifold Absolute Pressure) sensor right below the engine air box. The Turbo Tuner is not an ECU re-flash solution, but a embedded control solution that works seamlessly with the stock ECU. The turbo tuner provides real performance gains while it preserves the smooth and refined character of the car. The design features a soft limit circuit that avoids over boost which protects the engine from boost spikes and preserves drivability. There is also a temperature compensation protection circuit that lowers boost at elevated under-hood temperatures.

**Cars after 3/'08 can store engine codes showing an increase in boost pressure over the factory setting. For these models, we suggest using the Split Second Turbo Tuner 2 in it's mildest setting to prevent engine codes arising from excessive boost pressure.
