I had the tune for over a year before I went...

Good to know. Thanks! I can't really imagine a tune causing problems with smog. Car runs a less rich/cleaner.. And we're AWD, so we can't do a load test. RPM only.

good luck

CBRD suggests GSC S2's with any BBK turbo upgrade. I believe they said it moves the curve a bit to the left, which is always a good thing.
