This is within a safety range and will not damage the engine. The boost
pressure of the turbo is pulled up to gain amazing power and torque.
This allows the engine to show its potential power while the engine runs
within a safety margin.

In version 3, which inherits the level control adopted by Version 2, sensors
for control are added, demonstrating more stable performance.
- Increasing applications

Available for expanding many BMW turbos. Can be applied to various turbo
engines: N13, N20, N47, N55, etc. (The details of availability should
confirm to the following list)

:Increase Boost pressure
:Gain Horsepower

Reference Dyno result 328i/N20(YM2012)...311ps/6100rpm 45.5kgm/3930rpm Booster Chip at dial 9 with with 3DDesign exhaust.

Level control

- BC3 has a level controller which controls the tuning level. Nine steps of
adjustment are possible to suit tuning levels and the condition of a
particular vehicle.

- Recommended position is 6. Due to a possibility if incompatibility with
other parts or the condition of a vehicle, an engine warning light may come
on when the booster chip is in a high position.

Safe and easy

- Safety function
After the engine idle raises while it is cold , the BC3 suppresses output
temporarily and it operates with a safety function to protect the engine.

- Smart installation
Booster Chip 3 is easy to install, and it just connects between the harness
connectors of some engine sensors.

Version 3

The performance is ensured by know-how, field testing, and dyno-testing which came from feedback of version 2.

Moreover, the wiring unit which has high compatibility and quality is adopted, making it possible to control two or more sensors, offering a reliable product.

BC3 is composed with the original design housing and a waterproofing wire harness kit.

-Don't use with other parts which will change the boost pressure and the air/fuel ratio.
-When it is used with other parts which gain engine performance, a warning light might appear.
-Later, after installation, a warning sign might appear due to change in state of the vehicle by time, mileage, etc.
-The expected power and torque on the list are expected values under ideal circumstances and since the values are unequal due to the status and condition of each unique vehicle, please understand beforehand that outcomes may vary.
*note 1 : boost pressure may get hunting phenomenon at full throttle. But it doesn't affect the engine damage.
