Everytime I do emissions, I just switch back from Uberdata to the hack. I've passed 2 years already. When you do the hack, you won't throw any codes related to the turbo.

I also run 10 psi daily on my stock d16 for 2 years now with no problems with the car or emissions. OBD2 doesn't rely on the sniffer test, only CEL's...
