Question: new injector life expectancy

[MuscleTruck03]

Just curious how many miles you guys are you usually getting out of your new injectors stock or big sticks? Ive heard some guys say they only got 50k miles out of their new updated sticks. Also will big sticks last the same as new stockers?

Alot will depend on fuel system, good fuel and amount of time at higher pressures.

hmm ok, no one has any idea if they'll go another 100k or more?

I just had a thought....could the reason that replacement sets of injectors generally dont last as long as the OEM, even though they are "updated", be because the CP3/FPR are still "old" parts that arent running at peak efficiency right from the get-go because of high mileage? Maybe the only real way to find out is to replace them all at the same time?

I can kinda see that, but how exactly? maybe the fpr giving too much pressure?? Im sure keeping your fuel filtered good and that would help too

I would think with tuning the cp3 shouldnt matter but the FPR? yea I believe so. FPRs go out all the time in LB7s anyway, that slight rev and what not. Could the FPR be part of the LB7 injector failure!?!?! maybe idk lol
