I have a Predator 7135 and a standard 2009 Chrysler 300c 5.7 Hemi - it is an export car (I live in Denmark). We use octane 95 unleaded. Which tune for best fuel economy and which tune for best power?

use the 91 tune for your 95 octane fuel.

I can buy 92 octane here, is that the same result as with 95 octane if I use 91 tune?

Its the old RON vs RON+MON/2 story. All the answers are right here:

Great, thanks, I also wondered how it was possible to drive something called 87
