Hi all. I've been looking at this thread as I did the 3SIM mod on my Z4 3.0i N52 to make it have the same power as the 3.0si N52 (same as 328i -> 330i mod just for the Z4) and was also scared about smog testing. I used the oem 3.0si file from Bimmerlabs and passed smog today. Did not have to revert back to the factory 3.0i tune.
