BOV VTA question

Actually the turbos spool, but without a load (call tor torque) boost is not built up and is just dumped, so there's no perceived blowoff. When the car is under even mild load (moderate daily driving will do) the charge pipes are pressurized and that's the sound you hear. It's why there is a launch rpm for every EB car.
This car knows everything ..it knows where u work,what u eat,where you poop..it's very smart...no real reason to make boost when u free rev..a lot of cars that blow off when free revving are cars that have manual boost controllers.
I'm sure u could make the car do it but u would have to have the boost solenoid keep the wastegates closed that would force all the exhaust gases through the turbos which would create boost...everything would need to be done through tuning since the boost control solenoid are electronically controlled by the computer

Those people are doing brake rev--put it in drive, hold the brake to floor, and hit the throttle and then release it (rev it to about 3k). You will then get the BOV sound; have to put load on turbo in order to do it.

Not really..there is nothing u can do to put load on a turbo...wastegate dynamics determine what the turbo will do...if the car is programmed in a way to allow the wastegates to close at idle and during free rev then boost will build
Brake boosting may satisfy the parameters needed to make boost.
I've made a tune that turns our car into a naturally aspirated sho...so when u do that there is no way to put load on a turbo
