Recommendations on e99 injector upgrade
I talked to Bitterroot Diesel the other day. Super helpful guys over there. Trying to decide if I should do stock injectors but upgrade to 7AD/1AE injectors, ( or is all AD injectors a thing?), or do 30% injectors.
If the 30% injectors aren't smokier/louder I guess I'd do those, though I'd choose cleaner/quieter over a small HP bump. I don't want to change turbo, HPOP, or stress the tranny. Some custom tuning would fine.
Any recommendations on best route to go would be appreciated, planning on ordering tomorrow so I get them on Tuesday. Good news is they're only a couple hours away from me.

My understanding is that it has something to do with allowing the injector at the end of the run to get its full load of fuel but I don't know how it works. 30% is the nozzle size, and I believe that it refers to the size over original. So they would be 30% larger than stock. Injectors can have any size nozzle attached to them but they should be matched to other components on the engine. I have read that 30% nozzles work well with AD injectors. There are a lot of other guys here who know a lot more about it than I do.

Your selection of an injector depends on your goals for the truck. I wrote a post on October 1st to another FTE'r asking about an injector upgrade.
Instead of pasting it here, you may find some useful information in his thread, which I linked below.

After 200k miles on 160/30's and all the related upgrades to the engine...some for the 160/30's others because it was the "thing" to do at the time. I long for the days of 7 AD's and and AE, maybe a modded stock turbo.

I don't want smokie *** injectors, I don't want to replace my tranny, which shifts solid right now. You probably just confirmed me on the stock AD set up.

I would say 7ad and 1ae
the ad30 have a place for use, they add a little umph in certain situations, feel a bit more like 160/0.
the stock nozzles are, well, stock. They run smooth and tune easy with very few hiccups in the while scheme of things

Yes, my injectors have never been touched and work fine with 5W40 synthetic oil. That's if it ever comes off of the strike it's on. Right now it has some sort of electrical issue and won't start. That being said, I would take a serious look at the AD/AEs with 30% nozzles. From what I've read, the 30%s are as ESwift posted but don't require any goosing of anything else.

Here's a good post about the long lead injector. It's rare that a customer wants 8 AD injectors.
