Smog in CA and k04

I wonder how Ko4 tunes will pass now with smog stations also checking the ECU software in socal now.

In the past I’ve passed smog by switching my APR ko4 tune to the stock boost levels and emissions readiness while using spacers in my high flow downpipe.

However looking at the APR website it’s only the stage 1 ko3 tune that has a carb number. Doesn’t mention if their KO4 tune at stock boost levels will identify on the Smog computer as their stage 1 KO3 tune.

Thinking further about it, even if the tune registers on the smog computer as a stage 1 ko4 tune, that carb number will likely only match Golf R’s so it still won’t pass.

Maybe it’s time to just give up the Ko4 and reinstall my stock KO3 turbo and just swap between Stage 1 and Stage 2:(
Sadly, thats what I'm going to do. Just sell the K04 revert back to APR Stage 1, probably won't bother with Stage 2, having to keep reflashing.

You could always flash back to stock for the test and leave the K04. It will run fine as long as you don’t beat on it.

Yeah if you just drove it to the test and back and stay out of boost you would be fine.
