Banks derringer will detune when needed. I don't think any of the others will. There is a video being released this week by Banks that is going to explain their de-fueling option and compare all the modules.
Sounds like the Banks unit is the only one that plugs into the OBD2 port to monitor the necessary systems in order to de-fuel back to stock power levels when needed.
