Turbo lag 1.6HDi

[Westy]

I've owned a 2019 1.6 HDi 100 enterprise van for just over a year, in that time I've covered 26000 miles and it's currently on 96000. The van has been faultless but is very laggy when pulling away and has been since I bought it, something I've learned to live with. A friend recently borrowed it and commented on it and its got me wondering, is this standard with this engine? is there anything i can do to improve the throttle response, do pedal boxes work or is there something else i should be looking at?
Thanks.
