if you carry on using the evc then the turbo swapp will be fine but you will need to adjust the evc to cater for the smaller turbo.
You will probably have to increase the duty cycle to maintainthe same level of boost.
The TD04 can run 1.2 midrange, dropping to around 0.9bar at the top end.
If you remove the evc the esl will have to be changed to run with the td04.
Do you know if the esl is a version 1 or version 2 (live mapping) board.
