If you didn’t, this is a very good idea. If you did and I missed it, my apologies.

It's the bolt that holds the crank pulley to the crank shaft. It is vibrating loose while driving, most especially if I go past 3500rpm and enter boost. It needs to be tightened down after every drive or it keeps getting worse.
Maybe try a different bolt? I'm not sure what the shop put in there as I was on 7/12s for 3 months and couldn't do the install myself.
