Pete I don't know how you drive you ZS to only get 29/30mpg out of it.... I've had 40-45mpg out of mine consistently with the high level of tune...
I can get 30mpg out the mustang on an eco run (50mph cruise control during roadworks on the motorway)….

I'd question what the uprated turbo is/was and who has done the mapping; it'd give you more of an idea of expectations.
It looks tidy enough, although I also question what was involved in the engine rebuild and why it was required....
I've put mine though a lot of abuse, it's had a new fuel pump, and the head was ported, but nothing else on it has been changed (other than the HG a couple of times
)
