I've owned my 2010 300C 5.7 with MDS for about 3 weeks now and have been reading through some forum posts and looking at parts and have quickly figured out that it's a lot more complicated than my 97 Ram and much more expensive. I wanna start making some more power, nothing ridiculous for now, but really don't know where to start. I was wondering what I should do first, what kind of plugs do these engines like? What's a good tune? Thermostat change? Maybe some common issues or concerns I should correct first. I'd really like to eliminate the MDS and get some more throttle response out of it as well. Any help or tips would be appreciated, and if you guys know of any websites with good technical data or maybe where I could find a copy of the FSM to start to learn a bit more and get a better idea in my head that'd be cool too. Thanks.
