The tunes have to be taken out before the dealership can reflash your truck, after reflashing you can put them back in. There are some advantages to getting new flash, such as cold start issues and some other things. Some people have experienced a loss of mpg, however i myself have had the flash done and not seen any mpg differences.

Check your strategy. My '06 has he VXCF4 (original flash) which I have read is one of the better codes for our trucks.

No you don't want them to updata it, you will lose some low end. The flash you have is a lot better. I wish I could go back to it. My egts went up 100* after they updated it.
