Serious question, did I have my injector pop tester set way too low for years?
Spent 6 hours last Tuesday chasing a rough idle on a 6.7 and it turned out my pop tester gauge was reading 200 psi off the whole time. A $40 gauge from the tool truck fixed it and now I'm second guessing every injector I've ever passed. How often do you guys check your test gauge against a known master?
