It's $129 at the GMC Dealership I work at. Some side shops are a little cheaper. I use Chevron Techron in the black bottle. Pour that in a full tank of fuel, it has solved all my issues except the really really badly sticking injectors. (thats also the cleaner GM Recommends)

Injector Cleaning Those additives are not worth much IMHO... The best way to get injectors clean (I KNEW mine needed it with 175k on these in the pic) is to remove them and send them off to get done.
The guy that did these 175k DSM injectors did not just run some cleaner through them and then hope for the best. He REPLACED all of the seals, o-rings, pintle caps, and filter baskets with NEW parts and flow tested these both before they were serviced and after they were done. (The pics below are of the cleaned injectors, the dirty 175k injectors, and the flow sheet)
Results are in the flow sheet he sent me with the injectors. Frank also bagged up all of the parts he removed for replacement and returned them as well... Awesome work from this guy for a big whopping $20.00 per injector...
How well do you think those 'pour in' cleaners are going to work? and a better question is; What happens if the 'pour in' cleaner does get some stuff loose when that 'stuff' gets to the filter basket?
It will stay there on the basket and possibly reduce flow even more.
My advice would be to, spend a few more minutes removing them and get them cleaned correctly the first time.

On the DSM that these came off, it was a 7 bolt part swap for me. 2 for the the fuel pressure regulator (on the right of the rail), 2 for the fuel line (on the left of the rail), and 3 holding the rail to the head. I swapped the entire assembly vs. just individual injectors and saved time. 15 min swap.
The Helms manual for our Camaro and Firebird cars also tends to go into detail about removing parts as an 'assembly' and not as individual pieces.
(Without a doubt the greatest manual I have ever owned, Well worth the $$$)
Injectors and/or the fuel rail are not hard to remove... And the difference in the quality of the service is worth it IMO.
I hope some of this helps someone out.
