Sounds like the new ECU might have a different software version on it, that changes the wastegate position during idle and low throttle. Kind of like lagfix settings on the JB4

software definitely changes the WGs positions and would make it louder or quieter.

How many miles on the car, dme should be covered under the 7/70000 emission warranty.

i'd go with the wastegate theory

It is most certainly is the wastegate position changes.
