California residents who have modded their car?
Is there anyone on this forum who lives in California who has done a pulley and ECU upgrade? The reason I ask is that I want to do this to my SL55 and am concerned about the effects of this on the damn smog test in Cali. I would think that there should not be any impact but would like to know for sure before I do it. I am thinking of the Renntech upgrades.

Let me know where you get your SL done and the results. I'm planning the same thing.

I believe a lot of socal members modified theirs.... JamE55, Vic55, Benzoboi, etc. For Norcal, I think Treynor does.....
So far, haven't heard anything from them about smog issues.
