I have been wondering about wastegates on these turbos. From the pics in the website link...is that an internal wastegate venting into the exhaust?

It is the same as turbos have done for many many years. It is a simple dump into the downpipe. It simply bypasses the compressor inside of the turbine exhaust housing. These cars use an electronic wastegate that opens and closes it so it can precisely know how many MM it is open.

Waiting on a Pure800 to be installed in my a91 edition currently. Happy to share dyno results when the car is tuned.

any idea if your a91's ecu is even unlockable? i've read all a91's are locked and 7/20 and later a90's are also all locked

Not sure at this point. My build date is 7/20 but not sure what ECU the car has.

@Twisted Tuning and @[email protected] should be able to elaborate but from what i read ALL A91's are locked and currently no way to unlock, build date is irrelevant for A91's. 2020 and 2021 A90's before 7/20 build dates are unlockable after are the newer ecu which is still locked

I was prepared to wait for the ECU to be unlocked so not a big deal for me either way. I knew some 2021's could be unlocked while others could not. The car is not a daily driver so if I have to wait, I will. It does suck though and it is frustrating.
