Depends what you want.
Hdi- electrical, remaps big turbos to get decent power
Xud- mechanical, pump tuning and big turbos
Imo, hdi is easy, stick a remap on and that can take you up a few bhp.
Xud, turn a few screws and you have more power.
Both have pros and cons, after driving/being in both, I'd prefer a stage 1 xud
