Noticed on a few other runs and with our friends at IND made 20-25 more on average which makes sense given the different cities, dyno, etc.
The main purpose was to show the before and after in a controlled environment on the same day. A few things are for sure with this Beast is that they consistently pull the same #’s in stock form and tuned, as well as being underrated from factory. We shared conditions and SAE for those interested but I'm sure a 40 degree difference would yield another ~10-15 hp on the conservative side.
