Every manufacturer does extensive testing in product development and pre-production.
Yet consumers still seem able to inadvertently "field test" the already "professionally tested" products, and find failures.
Time and number of products, in the real world proving ground of regular folks who have no intention of testing the products, and just merely want to use them, offers the most statistically significant indication of a product's reliability... with all due respect to the product developers who bend over backwards to get it right before release.

Ain't that the truth...
Well, hopefully Herr Murphy will be out of the state this weekend. I'm dropping off the truck tomorrow afternoon for its DCR infusion. Should be ready Saturday afternoon, barring any corollaries from the aforementioned list...

Will do. Couple of days ago I was experiencing some odd electrical issues (the typical low-voltage dash warnings, random slow engine starts, iDash not initializing properly), and realized that my batteries were a few years old. Also, didn't realize that they were flooded batteries (doh!). So, got some AGM 65's to replace them. Once I get the truck back from the shop with the new pump I'll get those swapped out. At that time I'll use ForScan to set the battery type and then let it sit overnight to sync the zero time.
Got a couple of other truck-related things to catch up on, but depends on how late it is when I pick it up at the shop. Might just do those Sunday morning.
One thing I'm gonna monitor on the way home are the commanded and rail pressure iDash readings. Just want to see if those values differ from what I've observed over the past six months with the CP4. I'm not expecting anything unusual, but am curious.

Wow, I don't think I've ever seen mine go that high with the CP4, ~21K at most. What are your idle pressures? My CP4 is typically 3 to 4K.

I’m leaning towards an idash and monitor fuel rail pressure. If it’s consistently dropping then pull the trigger on a new pump.

Thanks, looks like idle is about the same as the CP4.
BTW, just noticed on your iDash PIDs that you're showing the Regen status. Did you know that you can set a notification trigger, and reclaim that existing Regen PID for use for a different PID? I used to display that Regen status PID, but set up the notification instead, and I like it a lot better. Banks has instructions on their site for how to do it, it's fairly straightforward, in case you're interested.

Not that I'm aware of, but you can do so with ForScan software I believe (but, I think it also depends on the model year; could be different for newer models, mebbe?)

Picked up the XLT from the shop on Saturday. They did a great job, I'm very pleased with the quality of the job (which was not unexpected, they do a lot of DCR installations as they're an S&S authorized dealer and installer). They also installed the SPE heater inlet tube that I previously purchased and was going to install at the same time I did the DPK, so that saved me some work as well. Now, I just have to get around to selling the SPE DPK, since I no longer require it...
First impressions with the DCR: Noticeably quieter than the CP4. Standing and listening at the open hood I was surprised at how quiet it was, as opposed to previously. Same while in the cab and accelerating, not quite the same sound level as previously.
Idle pressure seems the same, but noticed that pressure reported during acceleration seems higher. With the CP4 it hardly ever went over 21K, but now routinely reports 24K to 26K with the DCR, which may be due to the CP4 being a little worn after 75K miles. However, good solid pressure readings during all throttle operation. I'm very pleased.
