WRC have secondary air injection (antilag system)?

The ALS stands for Anti Lag System.
That it does is keeps the turbo building boost or on boost by recirculating air from the hot side of the intercooler back into the exhaust while retarding the ignition which creates a better scavenging effect within the engine. This causes the turbo to stay on boost.
The boost check is done to make sure the launch control strategies are working and to check the turbo speed to make sure the entire system is working correctly.
The ALS on the modern WRC cars is called a fresh air ALS. (explained above)

About the first time Toyota is clearly copying rival teams when it comes to aero.
EDIT:
Speculation: The renewed interest (they evaluated this before Mexico as well), could also be due to the brake issues Meeke had in Argentina. The dust entering the rear brakes trough the lower entry point could have been a factor.
Testing this why Haninen is entered for Sardinia ?
