standard, email, or cmr tune?

[08magnumRT]

Predator: u7135 v9r28
Vehicle: 2008 Dodge Magnum R/T
Mods: CAI & Catback exhaust

Would I benefit any from a more modified tune as apposed to the standard 93oct CAI tune. I understand my mods are minor, but I was wondering if it was worth the effort to have the tune adjusted to account for the exhaust. If that's all just crazy, maybe some suggestions on some modification I can make myself to WOT spark/fuel, etc.

Thanks,
Daniel

No advantage with your mods. Just tweak the fueling to get rid of any knock retard you may have.

Do you have any pionters on how to adjust the fuel and spark to get rid the knock

[Mike_Levy]

You gotta log the knock retard. Normally we get rid of it by adding fuel, but if the knock retard goes up when you add fuel, you have shitty gas and will have to start reducing spark.
