Hey Vendors! (and people who know stuff)- Injector upgrade asap!

I am sick of my injectors dropping out one by one. Another just died (third in 6 months, different each time)...

I want a set of 8 to just replace them all.

So, whacha got and how much shipped to 29410?

I have a mostly stock setup, all the info is in the signature.

Those who arent vendors, help a bro out.

I have 135k on the truck...plan to run it into the ground and I tow fairly regularly, but only a ~5000lb trailer. There are many hills here too (seriously, bridges everywhere) if that makes a difference.

I dont know where to start!

You could go with 190's and have DJ adjust your tuning to reduce your fueling until you could get a higher flow turbo...

With the detune of the chip, will the truck still be faster than with just the tune?

yes. there is more fuel to make you go faster. 190's can be pretty hot with a stock turbo though.

kingshaw, you should get a fass pump and dj's or itp's fuel kit. that will help keep a constant flow of fuel only to your injectors and will be cheaper than buying 8 injectors. fwiw, I was quoted 1800 for cass' 190's. the pump and fuel kit is roughly 1k. then if you're still having issues you already have the necessary mods to supply fuel to your new injectors.

I should have been more clear. They are going bad, and needing to be replaced. I dont think its a fuel supply problem...but I guess it could be?

well it could be fuel or air or water or oil. fass seperates water and fuel better than stock I believe and itp and dj's kits flow more constant fuel.

Actually darsey is right on! Its a very good chance one (or more) of the above is causing your repeated failures. Leading causes of injection failure include air or water being introduced and lack of available fuel supply. Before coughing up the dough for the new sticks I'd try to remedy the cause .

A FASS or AirDog along w/ a good regulated return fuel system should cure the fueling issues for the power range you are hoping for. Then I'd look at some 150-165's if you tow fairly often and probably 190's if not. Just remember you can always "turn down" a 190 through programming but you can't "turn-up" a smaller injector to make it flow like a 190. Either way you'll see more usable fuel available.

Stay Tuned

Is there anything I should mention to the shop I take it to?

Check the HPOP and fuel pressure? that it? Just curious, want to make sure we're not just replacing crap because its bad. I do want the underlying cause figured.

Dont injectors usually die around 100k-150k anyways?

maybe check ICP also. I know it has some kind of "output" that is optimal but I don't know what it is. I think I remember marc saying it controls the hpop which I would think is directly related to the oil the injectors get. I dunno I'm just talkin out of my arse basically, lol, but if you're gonna some things checked might as well get that looked at as well. I haven't heard of injectors failing at a certain milage. I don't think they should fail at all if the correct precautions and modifications are done to ensure they get all fuel and no air.
