In a manner of speaking, yes, so long as its common rail. Older diesel engines need the pump turned up manually.

2 routes
Tunning box or actual map
Tunning box can be removed easily but in essence just up the fuel pressure and therefore inject more fuel per injector pulse giving more power
remap adjusts other parameters
I have a tunning box at present which is meant to give 210 BHP and 310 ilbs/ft. Not sure what its actually giving out but its certainly quicker

The tuning boxes are ok if youre fuel pump is sound. Apparently on the Astra Y20DTH engines (mine) the fuel pumps are iffy at best and have been known to be the weakpoint, so overexerting them might give bad results.
That said people have had these boxes on for years and its been driven like its been stolen and nothing has gone wrong. Luck of the draw i guess, my luck is always bad though

But all those boxes do is put a resistor over something to trick the ECU into throwing more fuel into the cylinder.
That can't be good for the engine.

I dunno how it works  All I know is it can knacker fuel pumps, which are not exactly cheap to replace

That's not how th eproper tuning boxes work pow.
I had one on my fabia for a while before it was remapped and had no issues.
The only downfall against a remap is they can only up fueling and not boost so you don't get quite as much power.

very true
You get what you pay for. I wanted a remap but at the time no one did one for the new ECU's and theya re very expensive at present

Turbo Diesel = a big YES.
