Working great. Smooth accel, smooth idle, quieter than before.
I'm buying a second set for my other 7.3 before winter, because it's same age as the 7.3 I just had to work on. 25 yrs is the age when the o-rings tap out. Truck is at 326k miles, Excurs is at 257k. I'm sure mileage is part of it, but I don't need a breakdown far away from home. Great injectors!

I’ve had these injectors installed for about a week, they brought new life to my truck that has 328,000 miles on it so I’m pretty happy with them. I’m just waiting on the core charge refund but I’m sure it’s coming soon

Injector set
I replaced the injectors due to having to replace the injector cups. Clay assured me that using all AD injectors would not increase the noise of the engine true to his word that was the case. I took owner ship of this truck at around 220.000 miles and was please with the performance pulling our camping trailer without much effort. However the injectors made a world of difference. The idle is very smooth to were there is no vibration at the steering wheel at idle. At about 60 MPH no engine noise. While accelerating gently I would not have any turbo boost. Now I have between 2 - 3 PSI. I assume due to better exhaust volume which I can only attribute to the injectors. bottom line I am extremely happy with the decision to replace the injectors even though I thought the old one did fine, until I felt the difference. Would recommend these injectors.

Full Force AD Injector Set
Ordered these injectors along with new glow plugs and injector harnesses trying to get back to stock power after 315k miles. I wish I had spent the extra money and got any injectors but these. Ever since install the truck has terrible cold starts, smoke more than it ever did before, and has a rough idle once warmed up. These are also the loudest injectors I have heard from in the cab. Started going through the warranty process, cylinder 3 failed during a contribution test which led to the truck being down for 3 weeks while Full Force tested the injector and told me there was nothing wrong with it. I'm not sure if I just got a bad batch of rebuilds but I will never recommend Full Force injectors to anybody. I am to the point I would take my stock units back so the truck would at least start and idle good as I'm sure going into winter it's only going to get worse.

Full force is fully functional
I did the ad/ae stock set at 330k miles with new cups. Work amazing like fells like new again. The rr cup puller and installer made it a cake walk job. Btw truck did get a lot quieter at idle. More throttle response and back to 17lbs of boost. All stock truck

These injectors are a beast
These injectors made truck truck feel brand new I can't believe what injectors will do for a truck my truck before ran fine it was just slow and a little sluggish but not now it feels completely different but in time will tell how long they will last I have not found a bad review on these injectors so this is what I went with and I'm glad I did
