I don't inject anymore, when I did I did use Chris Lilly's injection a couple times and found I had to cut the salt in half. It will also make a difference if you are using a fine grind salt like a table salt or course sea salt, fine grind is going to put a lot more salt into it. Same goes for rubs which I rarely use anymore, and go with salt, pepper, garlic, and onion power, then make small additions of other things if you like.
