Thinking of buying another

[Slammed 66]

Hey chaps,

Just a quick one as it's quite late,

I owned a couple of D turbos around ten years ago and wasn't really too fussed about economy back then as I was getting free diesel, but now it's quite important.

I'm thinking of getting another dturbo, either xud or hdi.

What's best for tuning? I've heard bad reports about hdi reliability, is that true? Are they hard to get power from?

And finally, what sort of economy should I expect from a tuned XUD or HDI?

Thanks in advance

Ross
