2. Does boost decrease when I release the wastegate?
3. Does the boost remain under ~30 PSI absolute?
4. Are the cylinders putting out the same amount of power? (No misfire)
5. Is the fuel rack where I told it to be?
All of the above being satisfied, the ECU does not care about:
1. How much fuel is being injected into the cylinder.

Thank you so much for your help on this and letting me know which parts of the system are sensitive to change.
It looks like I could perhaps tweak a few of the readings from various sensors to run it as I would like it. Although if I bolt on a larger turbo then even though it might be set to 1 bar of boost, its going to be flowing more air than the stock turbo!
I will swap over that wastegate transducer with the EGR one to see what difference that makes, I am guessing as the transducer on the turbo side has been in constant use vs the EGR side which hasn't as much it will be good to see the difference.
