I had to do mine at around 54k but it was also only happening once running the tune. I just straight up replaced mine so I wouldn't have to disassemble again. Cars been running fine besides misfires for the past 6k miles.

My buddy has 50k on his car and started getting vanos
Codes when he switched to the aggressive tune. He's short on cash so I'm going to be helping him clean his or use my old ones so that's why the cleaning questions came up.
