can tune

What's the best tune for a 2006 Dodge Charger SRT8 for performance?

What octane gas and stock intake or conical? Run either the 91 or Diablo, whether you run 91 octane or 93 octane with the stock intake or 91 CAI or CAI Tune if you have an intake with a conical filter.

I run 93 octane & K&N CAI. Thanks for the reply Mike! Also, I saw a post which said don't use Shell gas, I was wondering why not?

[Mike_Levy]

Shell gas has additives which causes it to be very poor at knock control. And since the Hemis knock with just about anything, using a gas that doesn't control knock very well just compounds the problem.

Good info, I didn't know that about shell. Thanks so much!!!
