While the re-tweaked 6.7L Powerstroke hiding under your hood is definitely nothing to scoff at, there is always room for potential. aFe's Scorcher HD Tuner unleashes that potential by increasing turbo boost and fuel pressure, sending power levels through the roof along with fuel efficiency. Four adjustable power levels accommodate different demands, whether that means an extra boost for heavy towing or better fuel efficiency for long road trips. The sleek and low-profile assembly includes a high quality case and wire harness with factory style connectors ensuring quick and easy plug-and-play installation.
Four Distinct Power Levels
The aFe Scorcher HD Tuner Module doesn't just give you more power and better efficiency, but with four on-the-fly adjustable power levels, you can fine tune performance to suit different applications. Installation of this extremely powerful tuning system should only take around 30 minutes thanks to the plug-and-play design and OE style connectors. This powerful and versatile tuning device has been put through rigorous testing processes to ensure consistently reliable performance, and the best part is - it doesn't leave a footprint on your ECU!
Fitment: 2017 Super Duty 6.7L Powerstroke

Power Increase: up to +50HP & +85 lbs/ft TQ

Any one else?

But as you said, if you makes a change to any setting (that is NOT user changed at the dashboard level)., that becomes very difficult to hide down the road.

What YOU can do to cover the tracks is to (assuming it has) a OEM restore, this take it back to what was originally there. But that to has a challenge! It will restore back to factory either as it left the factory or with the last update. Now it gets really tricky IF you have not updated in some time and it restores to V .3, but the last update you did was to V.1...quite often in the world of Software you cannot skip a version update if you try all hell can be unleashed...most likely if it has a restore it will be to as it left the factory...

Rather, it installs in-line and gives altered sensor readings to the computer to trick it into changing some parameters like boost and fuel pressure. Where it will show is in the sensor logs if they are pulled and the tech sees a sudden instant change in sensor readings that disappeared the day you brought it in for service or repair (when you took it off). I also am not sure how safe these kinds of add ons are as they don't allow the computer to have accurate info from its sensors to make adjustments that may be necessary.
