As above, 91dB on acceleration, 96dB on back-off.
I'm pretty certain I won't receive a fine. The guy said the notice will be in the mail, but he won't fine me as I'd never been EPA'ed before. I imagine anyone who got tested that night who had previously been EPA'ed wouldn't have been as fortunate. Plus my car was otherwise stock, it would have been pretty mean of him to fine me.
