I have a 2016 Power Wagon with the 6.4 Hemi is this a Gen 3 Hemi ?. Id like to get more HP and TQ from it. What can i do besides the normal exaust and cold air intake kits ?, thanks Moparts.

getting a Tune, is your best 1st step.

I have an 18 PW. I guess a Pedal Commander really wakes them up. I think Diablo has some good tunes but no personal experience.

ric3xrt, why do you think of an SRT cam for something like this?

Another good thing to do is get rid of the factory y pipe, they’re horrible

The SRT cam is pretty good in a 5.7 so it should be even better in a BGE 6.4. It will reduce MPG slightly and shift the RPM range up a little and may make it less fun when towing something heavy but carrying around an empty truck should be a good upgrade. With a good tune the loss in the lower RPM range may not even be noticable.

What Dave said.
But I'll add this a good tuner will be able to work the VVT table to leave the cam Advanced longer than "stock so that should make up for any loss in low end grunt.
as for MPG, in My 2014 1500(4x2) when I had the stock MDS cam in the SRT392 Short block I was getting about 18MPG if I drove it like a respectable person. same as the 5.7 stocker that was in the truck org....but I am carrying around less weight then a 2500 4x4
