COBB Rolling Boost allows the driver to maintain a set vehicle speed while allowing the engine to build a set boost pressure (target pressure is the same value for BOTL (Boost of the line) and Rolling Boost, Note: BOTL does not need to be enabled for Rolling Boost to function). The speed can be dynamically set based on when the driver enters the Rolling Boost mode. The brake pedal is NOT used with this feature, so it cannot be referred to as "brake boosting", even though the effect is similar.
Entering Rolling Boost mode is done through the combination of holding the accelerator (Throttle) pedal past the minimum required point (Table - Rolling Boost Min. APP) and holding the cruise control switch in the SET position (down).
The Rolling Boost feature will use ignition retard (Table - IGN Main) to generate boost, and the throttles to maintain the target speed. The driver will keep the accel. pedal depressed (ideally WOT) and release the cruise control switch to exit Rolling Boost, allowing the car to accelerate with immediate boost response.
NOTE: This feature is only available on Protunes
