CarBahn Performance Controller (CPC):

The CPC is a plug and play ECU that increases boost pressure in turbocharged cars to dramatically increase HP and Torque. The unit has selectable maps through a Bluetooth app on your smart phone. You can download these apps for your smartphone through the Apple App Store and the Google Play Store.

Apple App Store: https://apps.apple.com/us/app/tuning-pro/id1508035080
Google Play Store: https://play.google.com/store/apps/details?id=com.sve.gmbh.tuningpro&hl=en_US&gl=US

These maps are designed to accommodate different octane fuels for additional increased performance. You can choose between 91, 93 and 100 Octane. As with all CarBahn products an optional powertrain warranty can be purchased.

If you want to trade your CarBahn Performance Controller in for software in the future, there is a $250 upgrade fee and if you purchased the warranty, it is transferable to the software at no additional charge!

Emissions legality:

A note on down pipes (removing the catalyst). We have run back-to-back dyno runs with the cat on and off and the power gain is much smaller than most people claim usually around 11hp. We all need to breathe the air. It is difficult to get your car its required emissions test without catalyst and it is illegal.
