Glad there has been some improvement although not perfect, shows your are on the right track.
How bad did the heat exchanger and intercooler look before cleaning?
How did it look after the clean, should look like new?
There is a possibility if they were really badly clogged if you didn't rod them though first the acid may not have been able to get down the tubes all the way to do its stuff in time before it stopped reacting.
As you say, prob worth doing the process again but rod out first, you will be able to feel if the tubes are still blocked.
