HAHAHAHAHAHHAHA
Goood luck bro, massachusetts sucks for this. I’ve been running no sticker for the last year for that reason after I rebuilt my 08.
Supposedly you can pass with one “not ready”. I know two other people with 6.4’s, both if them got stickers by having the e g r on, bulletproof coolers, and a straight pipe. Their tuning showed one “not ready” for the d p f but otherwise said it was fine and they passed. You might want to try a friendly shop with that one though. I never had the valve or coolers on this truck, or I might have done that.
You can check the readiness monitors on a good scantool, iirc my buddy’s versus does it.
Or you find another 6.4, tape a picture of your vin to the windshield, and have your shop run that as yours [emoji23]
Inspections are horrible now. You can’t even get tinted windows through, and I used to all the time.
If it was previously a massachusetts truck just leave the old sticker, you should be able to go a while without anyone noticing. Keep some parts receipts, say you just rebuilt it after it sitting a while and you’re trying to sort out a couple issues to pass inspection (which isn’t even untrue)
