how is the performance. Thank you.

What is in the owner's manual?

I doubt anyone here has a dyno to measure a difference. Therefore, all you
will get is an emotional or otherwise worthless opinion.

hmmm. 87 octane fuel is the only recommended fuel for this vehicle. The use
of a higher octane fuel could cause drivability problems in the long run.
Over a period of time High octane (slower burn) fuel could leave deposits on
the pistons and cause stalling, hesitation and even pinging problems. Just a
thought

The 3.5L 250HP engine requires 89 octane fuel in my manual.
87 is okay but they recommend mid-grade.

You didnt specify year, I looked up 2005 and 2007, it stated 87 octane

I have an 06 Charger SXT with the same 3.5L and it says to use 89.
