AMDP and ASAP both make tunes for the HO in no filter and filtered variants. The HP increase is less than advertised for an HO bc it's already running more boost than SO file (which is inline with why Velvet probably got that response from Banks - just not enough meat on the table to make that investment), AMDP covers in a YT video the true differences they are seeing with HO vs SO tuning and the magical turbo isn't much different than an SO turbo other than the water jacket to control heat better (paraphrasing).
Example according to Giovianni (programmer for AMDP) an SO turbo 80hp file is loaded on a HO truck it probably only gains 50 hp (just using numbers out the air) but if you dyn'd both trucks they would put down the same power (roughly) at that specific tune selection. Similar to why some of the earlier trucks have a +200hp file and the later models dont (yes there is some slight nuances with the turbos) but the trucks are starting with more hp/tq from increased boost and timing numbers from factory so the headroom for more HP is a lot lower.
A derringer is just essentially a boost fooler playing with factory ability to adjust for altitude just like the JB4 box does for Bimmer guys allowing for adjustments using the factory tables plugging into an OBD2 port just allows it to monitor how those outputs are effecting the engine via other telematics (gross simplification) no different than essentially any other inline tuner available. VW guys in the 1.8t days use to do somethign similar with a 1w zenner diode to blind the map sensor above a certain PSI so you could run more boost and the closed loop system with OxS would adjust fuel accordingly. Instead of spending $0.15 for a diode you spend $500 for some OEM connectors and datalogging/monitoring. Another option similar to the Derringer is the Edge EZX inline module (which unlike Banks) is compatible for the HO trucks (https://www.edgeproducts.com/products/in-line_chips_and_modules/ezx/parts/12713).
