Can you tune the 300 to only run on 94 octane? Possibly more power?

If you install the tune with a completely stock car and then later add an axle back exhaust, do you need to request new mapping files?

I know they are working on a supercharger, something I may invest in down the road once my warranty expires.

Rather save the $5k at the dealership and go this route.

The tune will work well on 94 octane on its own. We are upping all the ignition maps, so ignition learning still have more headroom to up timing on its own.

The stock and exhaust tunes are the same. The header tune will be different.

Rafi said once the RWD is fine tuned, we can do a group buy. In about two weeks.

If the tunes are the same then does running stock exhaust run a little richer/aftermarket run leaner?

I have a couple questions. If I install this on my leased vehicle, will the dealership know when I take it for regular maintenance? If so, can I switch it back to stock before I take it to the dealer, will they still see the ECU has been modified? I'm thinking about buying the car out early...So if I've fully paid the car off, and take it to the dealer, will they void my warranty? I already have an axle back and various other cosmetic mods done, I still haven't taken it in for it's first oil change yet.. Still under 4k miles.
