How much does the courtesy letter say the fine is? Usually its ~$400-500+. I don't know what you do for a living, and how long it will take you, but if it's going to be a few days of work where you have to take time off, just pay the fine.
If you had a 95 you could've kept the EEPROM since we dont get tested for OBDII readiness.
Why did you get pulled over? Was their probable cause just because of the big fart can tip that most of us with modified DSMs have?
