The big three, intake, exhaust and tuner. You stated you did the exhaust? Check.
The current intake is said to be very efficient so just add a K&N or Spectre oiled element over the paper. Trinity is said to be the best. And just recently said on another thread about BullyDog double dipping when or if an owner decides to sell their BDGT, it's an extra $250 to transfer. The trinity is $100 more than the BDGT, and definitely worth it. Lastly, lay off the heavy foot and drive normally. Meaning, don't bog it, and then on the other hand, don't dog it. This, I truly believe will get you those magic numbers like many of us have achieved IF!...............that is truly what you are looking for in your new Ram. Great luck brother!
