Used to rebuild injectors with a hand pump, now I'm all in on the pop tester

Back when I started at Thompson Diesel in 2018, I'd break down injectors on a bench with a simple hand pump and just guess at the spray pattern. Last month I finally got a Bacharach pop tester after my boss got tired of comebacks from bad injectors. That thing lets me dial in opening pressure to the exact spec every time. How long did it take you guys to switch over to proper test gear?

Yeah that Bacharach setup REALLY changes the game on consistency.

But does it actually hold up when you're running a full hybrid or quad setup with different spacing? I tried their single plane setup once and the consistency was night and day compared to the older multi unit stuff, but it seemed to fall apart a bit when I stacked multiples. Are you seeing that same kind of drop off or is it more forgiving with the newer runs?

And I bet @patriciah51 would agree that stacking them actually improves the feedback loop.
