Burger has been very coy with dyno graphs showing meaningful HP gains on pump gas for 2021 cars. Seems to show gains if you go with E50, etc. but pump gas... haven't seen much. I don't think a 2021 owner is going to see 100HP and 100 lb.-ft. gains on a pump gas map with the JB4. Not saying it doesn't exist--just that I haven't seen evidence of it.
