Common Questions

What does Stage 3 add over Stage 2?

The dedicated 8-rib belt drive. It is the same drive architecture ProCharger's fastest customer cars run, and it is the right base if your power goals will grow.

Does it include tuning?

Yes. ECU and TCU tuning is included with every complete system.

When do I need the crank support?

High horsepower and high RPM combos. If you are headed past four-digit power, add it. Note that it requires sway bar removal on this platform.
