Needing some info on how to get an h&s mini maxx on my 2014 dodge cummins mega cab

 

Not possible. The 2013 and 2014's have very limited performance parts. Edge Juice with Attitude or TS Performance Stryker.

 

What would be the best tunner or chip to put on this new piece of

 

If I were to put one on my 2014, I'd go Edge Juice w/Attitude. With all the features and up to 6 power levels, plus no footprint when you remove it, it makes for a nice unit. You can add on a pyro or other sensors if you want as well.

The Stryker is non-adjustable, plug and play simplicity.

Both units retail for similar money, so why not get the monitor, adjust ability, and all the other features?

BullyDog GT Diesel Tuner is an option, but I've never been a fan of BullyDog.
