I've been a Deatschwerks customer for over 15 years. I went to start my 240 truck the other day and it was clearly running on 3 cylinders. I narrowed it down to cylinder #3, then swapped plugs around. It stayed at 3. Checked the resistance of the injector and got mega-ohm values (compared to something like 11 ohms for neighboring injectors). No big deal, those injectors have been in there a LONG time. It happens.
So I hit up the Deatschwerks website to see what my options are. Didn't see "single injector replacement" anywhere on there so I called them up. No answer. Called back an hour later. No answer. Left a message. Mind you all of this is within their stated business hours (and not at/near the end/beginning of them). Called back 2 more times the next day, again no answer.
So I start asking around for anyone who's got similar injectors around me (used). Find a guy that has a set from a Subaru that should work. He says I can have them for free, but I should get them checked. So I fill out the Deatschwerks order sheet and send him a copy of it to include with the shipment of the injectors to Deatschwerks. They offer fuel rail servicing and injector swap out as well, so I ship my loaded rail in to them for the swap. I request they also pull the injectors that are there and flow check them, then send them back (never know when I might need a spare).
In the mean time, I swap in a stock loaded rail and crank my base fuel pressure and adjust my tune so the vehicle is mobile... diligently staying out of boost.

So a few days goes by and I call Deatschwerks again to see if they got the shipment, etc. Someone picks up this time and says everything is good, the shipment is on its way back to me. He takes my credit card info and charges me what seems to be less than what the website suggests the pricing should be. I confirmed all of the work that was supposed to be done. The guy on the phone agrees. Cool... maybe I got a frequent flyer discount or something.

So I get the shipment in a few days later and the fuel rail has been stripped of all of its zinc plating. The new injectors are in there, and they are numbered 1-4. There's a flow test sheet along with it with results for 1-4. There's also a pack of my old injectors, which have clearly been cleaned up and rebuilt with new O-rings and pintle tips and such. The injectors on the rail don't appear to be cleaned up or have any tips on them at all... go figure. There is no flow sheet for the original injectors. ^There's the rail. It looks like spotted d!ck now. I suppose if the plating was already questionable, their cleaning process would have stripped it completely. Still, now I have to do something about this. It would be cool if they offered a refinishing surface as well, OR if they told me their process stripped the plating off, so I could get something on order.
I end up picking some of this up after doing some research:

I taped off/bagged off the injector bits and hanged the rail up in an unused warm room in my house for paint. 2 of the injector cap screws were VERY loose/had gaps between them and the injector covers when I removed them. The good news is the zinc spray I got seems to have worked pretty well. The coating is nice and not primer-like. The color isn't like the original gold, but I don't hate it.
^There's the completed project, with the old injectors looking fabulous.

Anyway, just curious if anyone else has used them lately and what your experience was. I'll be swapping this rail back in as soon as it warms up a bit. I HATE dealing with fuel when its below freezing.

I stopped using them when they stopped supporting the forum. That's just business.

Good to know. Who's your go-to fuel injector servicer/vendor now?

Don't really have one, but I'd probably go with whoever Tony (UMS) recommends.

BTW, David should be in touch with you soon.

Have these become exceedingly rare? I always just popped in some used ones without testing (other than with a multimeter) and 90% of the time they were fine.

But this is now 15+ years after I used to mess around with the good era of Nissan.

Well mine are larger than stock. With turbo applications, air/fuel ratio becomes a lot more critical. You definitely want to have a good match between all cylinders.
Another note- Krista from Deatschwerks contacted me and was very helpful with the situation. She's a sharp cookie that wanted to get to the bottom of what exactly went on with this order.
The other night I went to install the rail with the new injectors and realized they only gave me 2 adaptor harnesses/clips for the injectors to connect to my old harness. Not sure what they thought I'd do with only 2 adapters for 4 injectors, but whatever. I hit up Krista again and she's taking care of it.
So I guess the moral of the story is it was a bit of a weird order with limited communication, but they are definitely interested with making it right. I'll post up pics/results when I get everything installed.

Update- nothing has been taken care of and this is still ongoing. Krista handed it off to a guy named Mark.

I know a Krista. She's awful.

I like the majority of Marks I know so that's a god sign.

I wrote a salty Email and Greg also sent some messages. Another couple hundred bucks and I'm told there's 4 new injectors on their way.
So if anyone wants some 550cc subaru injectors, let me know.

Apparently, this is what passes for 'customer service' these days.

How about do it right the first time, and if there's an issue, make that your #1 priority?

Novel idea, right? Nope. It's how I run ALL of my business ventures.

My last experience with them was less than stellar as well. Like you, they just seemed generally bothered by me trying to do business with them and screwed up my order as well. Ended up getting ID1300's from T1 Race Development. Those injectors fixed problems I didn't even know were related to the Deatchwerks injectors I had been using. They used to be awesome. But that has not been my experience anymore. I'm sorry you're having trouble as well. Problems like that are so frustrating and time consuming.

Good to know. Thanks for the feedback!

Ok, time for an update. Here's the injectors installed to the rail with one of the adapter harnesses they gave me: One side looks like this: The other looks like this: Deatschwerks assures me they've never had these in stock, can't get more, etc... even though they put 2 in the box with my original shipment.

So, enough was enough and I said just ship me a whole new set. The car had been operating at limited capacity for a month at this point with the stock injectors. Due the the fiasco at hand, they sold me the new set at half price. That was cool of them.
So, new 550s show up and I pop the subaru injectors out. Looks like they used 2 different kinds of lubricants on there, or maybe it was just bits of my fuel rail flaking off and mixing with the lubricant/o-ring. So if you're reading this and you're in the market for injectors, I'd skip the whole "send us your fuel rail and we'll clean it and install the new injectors" service. There was a good bit of corrosion and such in the area. It might have sealed ok, but we'll never know. I went in there with brushes and sandpaper and cleaned it all up and shot it with some more of that galvanizing spray. The new injectors popped in fairly easily.
There's some little isolators that go on the top caps for the injectors. They sent me some new ones with the loose injectors they sent, but it doesn't look like they replaced them when I had the fuel rail "serviced" and other injectors installed. The ones I pulled out are on top, new ones on bottom. All installed.

Worthy of note - they call these "550cc injectors", but the flow tests show they are really 525s. Its not a huge difference, but its also a good bit more than "nothing". It would be cool if they could tell you what they flowed before they shipped them to you. I was on the fence about upgrading to something bigger to begin with. This would have made that decision easy.

Completely unacceptable.

I remember when they were small-time, selling rebuilt 370cc's to SR swap guys.

Guess if you're not building a 2,000-hp GTR, they can't be bothered. It's a shame, because they were a good bunch back in the day... and they used to support the community.

I'm glad they at least attempted to make it right by giving me the discount on the replacement set. But yeah, I agree, it seems like they have some questions they need to be asking themselves about quality control, shipments, returning phone calls, picking up the phone, and returning emails.

The whole vibe is just weird. Take a look at the flow sheet I posted above compared to the original one they sent me for the subaru injectors... they are totally different. Maybe because 1 is a "pre-test"? They convey the same information... Also, even though they invoiced me for the testing of the original injectors that were in my rail, I never did get results. The last guy I talked to on the phone said they were "all bad" and therefore didn't get tested... I knew 1 was bad but wanted the others cleaned and tested so I could have a replacement ready to go if this happened again.
