Engine Malfunction! Reduced Power Warning

Is this probably because of the DPF? Haven't had it on the highway in a few weeks and this 2011 35d has 101,000 miles. It seems to run great and does not seem to have reduced power. I'm thinking it is measuring too much of a difference in the back pressure before & after the DPF & I haven't had it on the highway to do a regeneration cycle. My DPF delete pipe is being built now so will be getting rid of this issue very soon. I'll post a thread for the DPF delete/tune in a few weeks when it's complete.

That is a generic "can be due to 50 different things" warning.

I know you are planning the DPF delete. Interesting that such a plan would drive you to that assumptive diagnosis... could be I guess, but really a shot in the dark without any other data

Did you pull any codes at all???

I don't have a scan tool. I have an OBD/USB cable for when I loaded my Evolve reflash on my M6. Anyone know of a code/scan program that works with Mac? I had to use a friends laptop to load the Evolve tune since they didn't have the ability to use Mac almost 2 years ago when I did that. Just found this app. Anyone use anything like this before? https://www.yhasi.com/index.php

I'll chime in ignoring the risk of further accusations in incompetence
You will not find any decent working on MAC. A good quality older lenovo laptop could be bought for as low as $100 on Ebay. We are using Bavarian Technic cable, very good at code reading and impressive at datalogging. I spent many months to find out something that gets close in sample rate and output format, but didnt find anything. Good tune without datalogging is not going to happen.
