I have a tuner chip I used in my 2015 Ram Big Horn 1500 Crew Cab with a 5.7 Hemi.
I traded this truck in but kept the chip.
I purchased it on Amazon from the company called Power tune.
High performance tuner Chip & Power tuning programmer boost horsepower and torque.
I did use the chip it just plugs in it's not adjustable seem to get more power and possibly more torque. It is hard to tell on my truck because I had a cold air intake exhaust and other modifications.
I believe on a stock truck it would be more noticeable.
