Yea I about flipped when i priced them, I was gonna put a set of pensacola reman's in and new cups but i didnt have enough cash for new cups and injectors. I think i only got one or two going bad. It only smokes when cold out and trucks at running temp. when truck cold it doesnt do it. I going to a buddy today and gonna use his efi to check balance rates.
If you need any GM parts,, get with me first as I get a pretty good discount and can ship them to you probably cheaper then you can get them down there.
just got back home from my buddies and looks like numbe 6 injector and possible 3 need replaced. Number 6 balance rate was 5.89 and number three max balance rate was 3.99 rest of them looked to be in spec.
