Seems like every single place I find that actually lists a " chip " for the new 600 Cummins doesn't have them in stock. Naturally I'd like the best, but I'm at the point where I'll settle for anything that is in stock that can be shipped the next day, not 2-3 weeks from now.

Since I'm a green hand to the website, if posting links to retail sites are not allowed, please PM them to me.

Thanks!
