Thank you Brusk. I have contacted CB Engineering and they recommended Malone or Green Diesel. Both sites didn't seem to categorize the stock specs right, so I have reached out to them for more information.

Aside from no longer dealing with DPF regens, have you noticed any perceivable gains in performance and/or fuel mileage?

Unfortunately the vehicle I bought has been a bad example. Somebody that had to right working at a dealership has broken several bolts, not tightened things down properly etc. I've been through the hell of a leaky oil cooler, broken swirl valve parts etc. Latest is a brittle inlet pipe that fell apart and wiped the turbo. Putting the turbo back together I dropped a bolt that happened to find an access panel that somebody didn't put a cover back on. and it goes on and on. lol. I hopefully will have it back on the road and not experience any further problems tomorrow but I did notice the oil pan is also leaking so it might be torn apart next week to get that fixed.

I wish I would have talked to him first as those seem like better financial options than what I chose but the biggest thing is just getting all the options turned off in the ECU.

Sorry to hear that and hope you're back on the road soon. I've had pretty good luck with mine over the 90K I've owned it. The only mechanical items were a speed sensor in the 7g-tronic transmission which necessitated a valve body replacement (problem on all early 7gs) and then some duct work for the turbo splitting and separating at high boost causing a limp condition, which was easily fixed by replacing the duct work.
