Tren cough happens when it gets into the bloodstream too quickly. Obviously Ace is more likely to do this. It can also happen when you nick a vein. It can ALSO happen when you inject into an area that is rich in microscopic blood vesells. Your body will generate them to send more blood to areas where it is experiencing trauma such as... yep, Injection sites. It is best to rotate your injection sites so that you only hit the same spot AT MOST once every two weeks. Depending on how frequently you are pinning two legs and two delts may not be enough and in your case obviously isn't. Can you work on some new sites. I am fairly confident a brand new site will not give you the cough. Give the old sites a few weeks to calm down before pinning there again.
Another successful pin today in the right delt with no issues

So I should use some new spots? Like a sniper - shoot, relocate...shoot relocate. Haha!
I like triceps but I'm pinning 2ml at at time (1ml of test400 & 1ml Tren e 200mg), I'm thinking that maybe a little much but my delts are holding up fine.
Calves - no fucking way! Did that and was crippled! Same with biceps
