Hyde,
I had the clock spring replaced about 6 weeks ago, before I heard on the TDR about the recall ( or got my recall notice in the mail). I also bought my truck in CA, took it to a different dealer to fix it, and as far as I can tell, they didn't do a reflash. I have heard that when they do a reflash, they put a sticker or something on your truck under the hood up near the fan shroud so other technicians will immediately see it and know when the truck was reflashed last. Nothing like that on mine, and it also runs the same as it did prior to new clock spring.
Dealer didn't even flinch at all my performance stickers all over the truck (DD, Amsoil, K&N,... )
