also yes the truck is registered in California and the PCM reads ATA2. Build date says 12/98 too! So it’s not an early 99
12/98 build date is indeed an early 99 fwiw. There were no 1998 model year Superduty trucks, was all new for 1999.
Yeah I would not want a 2000 rpm high idle either. Did it come with documentation saying what the RPM should be?
Kinda stumped by the ATA2 code on your PCM. The main difference is GPR (Fed) vs GPCM (CA). They do list different PCM families; the ATA2 is a DPC-431 and the AWA4 is a DPC-401. I assume that is due to different pinouts required for GPR vs GPCM wire harness. So it looks to me like you should need the AWA4 since you have a GPR. Seems like I now enough to get confused here but not enough to help.
If you got gauges to go with that tuner then what can go wrong that will kill the engine during a short test drive? Seriously I can't think of a scenario that wouldn't be averted by simply keeping an eye on exhaust temps. It's not like the injectors will become suddenly possessed and start spinning around in their bores vomiting diesel and hydro lock the engine... They can't do that right? We might need a priest.
No you’re right!!!! I just currently don’t have any gauges since I didn’t think I’d need it staying conservative at the 50hp/tow tune. I was just afraid the tune was gonna be too hot and blow the injector tip or something. I’m more used to mechanical diesels so I am sorry if I sound dumb but outta everything I am just misinformed on these newer diesels !!!

Not confusing!!!!! It’s helping me understand more!
To answer your question about what’s the set high idle on these tuners, I see everyone say anywhere from 1100-1200rpm max on these Edge Revolver tuners. Part number is 14004 and it’s a AWA4 master code tuner so you’re possibly right on it working for me!
Will just use the tuner after I buy the edge insight for it with a pyrometer !

Don't sweat it, we're all new at some point and anyone that forgets that is just an a**hole in my book. I've hung around here long enough to get fairly confident in my ability to diagnose and repair one of these trucks without a second thought, that is until it's my own. Then all I can do is second guess myself. Human nature maybe idk, but we all do it. We just got to remember to stop, breath, and think.
Some one just set it high because it was for running equipment or something like the power take out. The tuner could adjust it if you wanted. And some of the last 1999 trucks had intake heaters and late turbo set ups. My neighbors stick 12/98 had no cat! but the 2000 on I believe did and the auto didn't. Mine does because it is 9/98.

Sorry, “newer diesel” made me chuckle. Your truck is 25 years old. Around here we’re always talking about our stuff being old dinosaurs.
I’m not criticizing, just struck me funny to hear someone consider what we call old as new.
For the CTS3 there are other add on packages that may make sense if you’re wanting to have a few more gauges. I forget that they’re called exactly but add like the EGT and fuel pressure gauges. The CTS stuff gets expensive quick but most people like them. I have a very old original version.
I’d call and get some recommendations for the kit before making a purchase. https://cncfab.us/search.html?q=Cts3

Thanks man I appreciate you all being patient with me! I called edge today and they confirmed that they DO NOT make anything compatible with my pcm code which “explains why it behaves like that on the high idle” they said. So I guess I am back to having no tuner and no way of being able to return it!

Sadly I guess the high idle problem was just the tuner not being compatible
Well lesson here is don’t be a ******* like me and check your pcm code FIRST BEFORE you buy a tuner HAHAHA
I like udsuths idea of getting a PCM to match the tune. Kinda elegant solution.
But for chits n giggles I'd try to run the tunes you have. A 2k high idle tune is stupid but still useful and not necessarily a problem. Just get the EGT installed first. All the cool kids have them. Then you can monitor the biggest danger to the engine as you test the tunes. Maybe whatcha got works ok.
And be very careful about the smog requirements for your truck. Be 100% sure.
Tell ya why. Grab a beer.
My In-laws are 87 yo and stopped driving. Smart. They gave my wife their 2015 Jeep (I got the Jag ). Jeep has been on the list for the U90 emissions recall for like 9 months already. Now the tags are due but DMV refuses to issue tags until dealer advises the recall is completed. The Jeep is on the list for repair at slot 154. One critical $18 part is on national backorder and dealers are rationed 2 per week. Do some math and you can see the critical recall will not happen until middle of 2025. Neither DMV nor dealer will give us a way out. So we get to drive on expired tags for a year. Our gov't is absolutely stupid.

So CYA on smog stuff my friend.
I don't think me and "elegant" have ever been in the same zip code let alone the same sentence. So thanks for that, another check on the ol' bucket list.
Have you tried getting the dealership to pencil whip some paperwork for you to at least stay legal or is Dodge willing to cover the fines and penalties associated with their eff up? I know here in OK it's a dollar a day every day after the 30 day grace period up to $100, and it starts over the following year. So if it's not fixed by the time the tag came due again it's another dollar a day. Of course as I type this it occurs to me we're talking about California. They probably throw people in Azkaban for fudging paperwork.
I would double check your getting a pass on CA smog check, CA has made it a habit of changing the rules after the fact and making it your fault. My truck is e99 (5/98), DPC 412, VCQK code, GPR (Stancor now) and catalytic convertor. Every two years my smog check is something I dread, my truck will not run for inspection, it shuts off, some techs know this quirk, others just want to send you home. I had run a Banks Stinger Plus system on my truck for over 20 years, (Banks has CARB approval). I don't if any other Tuners are CARB approved. I decided to try the Hydra for the ability to run different tunes for different uses and have been impressed with the performance it provides. But like you, they didn't have a stock tuning file for VCQK code. They recommended to try a different code file, forgot actual code, but it loaded and has run excellent since day one. Back to smog, I'll be programing back to factory programing and take switch out and put it in my pocket when my next smog check is due. Next year, fingers crossed. Only Diesel in CA that got the pass ran off highway Red Diesel and that has changed dramatically in the last couple years, with fines and equipment upgrades in the $$$.
