I know, like I said in another post, I have had this 3815 for years and only noticed this after I updated the tuner to the latest version of everything. I de-programed last night for comparison and it felt absolutely no different than when the tune was installed.
Anytime you go back to stock. The computer will use the highest "default" setting. When the sensors report back to the PCM for "adjustments" like fuel and spark knock retard. The performance will start to back down.
We have not de-tuned any of the Hemi files, if anything. Making them better.
