Sticker on the ECM maybe? Otherwise not without some expensive equipment to pull the tune and see what's there... even then you'd need the skill/experience to know what you're looking for.
Can we chill with the negativity? The world absolutely sucks right now with everything going on and people are stressed and some are even uncertain as many folks jobs have been affected. I know I come to a forum to discuss my truck and get away from all the noise on the outside, it's somewhere...
I've umm, put my truck on a weight loss myself. The exhaust fell off and I had to finish it with a sawzall.. which was a bit disappointing in case I needed to put it back. But, if you have basic mechanics tools you can do it yourself.
