    Hello all! I have a '12 1/2 ton crew cab with the 5.7L. Since it's getting up there in miles (120k will be upon me soon), I was wanting to make it breathe better. I'm looking at getting a CAI, exhaust, and potentially some headers. I'm not sold on anything yet, but what are some of y'alls favorites/recommendations?

    What I'm leaning towards:

    CAI - VaraRam
    Exhaust - Craven direct fit (progressive). Possibly the Borla S kit
    Headers - Doug Thorley Tri Y

    It should be noted that I live in a county without emmission testing.

    IMHO--this would make a good street package--check with Moe's Performance(a vendor on this site).

    I'm actually wary of tuners. A coworker put one on his 2011 big Horn, and it locked his truck into 4wd low.

    Some problems can be user error---thus a custom tune with good support

    I've been putting Diablosport programmers on Hemi powered cars since 2008 and as long as you follow the process, there are not problems. It's not something you should rush.

    The benefits are clear...if you have more air in and more air out, you need that programmer to optimize your air/fuel ratios, spark and timing. They work really well and

    I am a big fan of the Diablosport programmers and custom tunes. I have one on my Chrysler 300 SRT8 based on a Diablosport Predator unit that was done on a dyno by a trained tuner I had a custom tune on my 2014 Ram 2500 Big Horn with the 6.4L HEMI as well, using a Diablosport I2 programmer. Hemifever did that tune and the results were amazing.

    You are really shortchanging yourself, and your truck, if you don't put a tune on it.

    Thank you. Starting to really dig into the research now. Still a few months off.
