I just bought a 05 2500 with the 6.0 liter I put a cold air intake on it and i been looking around at some programmers Im looking to improve my mpg i was looking for some direction on what a good one is and if it's worth it? I would apprictiate it

 

Add an exhaust system. You are drawing in more air now, but not letting it exhaust for a complete loop. I have the Superchips Flash Paq programmer with teh Internet update etc... I have had good luck with mine. I had the Hypertech III for my 1st programmer, but it made my truck clatter the whole time. Thats why I swapped to Superchips. However after I had the Hypertech III the Hypertech Max came out, but I di dnot try that one, but a few of my friends have it and like it. Most of my friends just get their ECUs tuned by a professional.

 

You need these 2 things in this order:

1. exhaust
2. Blackbear custom tuning. Google it and thank me later.

 

Tuners: Nelson Performance, Wheatley Tunes, Black Bear.

Exhaust: Flowmaster, Magnaflow, Borla, etc... your preference. I personally have a Flowmaster Clone that I am happy with.
