Did you measure 0-60 times, 30-60 times etc.? Resp. is there objective data from before/after the pre-chamber drillings? A "feels faster" can be all or nothing but imagination. Oh dear - I'm not doubting your effort, please. It's just in my kraut nature to strive for exact data & precision, you know what I mean? Only hard facts satisfy my little german soul
And you know what? I love the harsher sound of truck etc. engines! MB engines are much too soft. But then perhaps this was the main goal and reason to keep the pr-chamber technology for such a long time. To make the diesel go uptown, keep it quiet and manered, do away with it's tractor image. And maybe this is - who knows? - why they made those holes so smal. Probably was for emissions (smoke is not the only variable in diesel exhaust emissions) too.
All in all - I'm interested in this! If there's something to gain and make that sluggish engine a bit more reactive
The only long-term concern I might have is stress to the pre-chamber. With holes too big the tip of the chamber may not conduct heat quickly enough. And is under higher thermal stress (see p.e. here )... Respectively; I'd fear the tip may fall off if the engine runs "hot". Do you monitor your EGTs, MTUpower? I think this would be very interesting too as a before/after. If or how they have changed
Don't mind me, just thinking out loud... And as said, not doubting your or anyones effort!!! I just want to know stuff as precisly as possible I tend to make science out of everything. So I'm not euphoric but always a bit doubtfull.
