The zealots of the "Save the Planet" crowd will complain at both of us. But I agree with you, That is why the Rest Of the World do not use the SAI system. And the Euros have excellent green cred?
The same problem exists in Architecture. Trying to get an Architect/designer to understand lifetime cost of 'green' designs or total end-to-end carbon footprint is very difficult, Because they are pandering to emotions not trying to find the best for the planet.
In theory , you can do this yourself. Just send your DME to ECU Doctors- $500

If you Search(I did !) there are hundreds of Posts from smart Porsche diy guys bewildered by unfindable faults in this finicky system. The individual components are simple and the system looks simple on paper but fixing it is nonsense.I say that because if you read these threads to the end , the fix is seldom pinpointed. It could have been Drive Cycle or some other Readiness trick. Meanwhile people keep failing SMOG tests ,waste a lot on unnecessary parts, waste money with Mechanics. It is very easy to cause collateral damage when working on this system.Often you need to remove Bank 1 inlet manifold so it is a lengthy task. Many cases have multiple futile, expensive attempts at a fix. All this for a system that runs for 90 seconds max at start up. There ae better ways to save the Planet imho than throwing time and money at the SAI system.
Oh and those who thought they fixed it - some are back a few months later with the same Codes- again !
Even Jaguar don't have this problem ! Why? They used Delco !
