Dan aka Fastman is basically retired now,and is only doing throttle bodies to catch up to his existing orders,and then i think he will be done,he's pushing 70 now. Your stock coil packs are better then most after market coils,so save your money on them.Copper plugs are more efficient then irridium plugs,but you'll want to change them out roughly every 30,000 miles ,and contary to Maddogs post about long tubes,they actually generate more torque then a stock manifold or shorty header,and unless they've changed the factory exhaust manifolds lately,you're 6.4 should have basically a peanut port cast iron log manifold,not a shorty header manifold. Tuner i'd look at HP instead of Diablo with a custom tune from somebody like Ryan Hogan /Flying Ryan Tuning or Mark Rogee ,Rogee seems to be specializing in the heavy duty truck tunes more then most tuners these days.I bought a Pulsar from Edge, and it was terrible. The thing kept killing my Throttle in the middle of the road (TPS light would come on and I would lose my peddle completely.) It also kept throwing detonation codes under hard acceleration with every setting. I would not recommend it. All of my reading has basically pointed at the same ting. Get a tuner with a PCM swap and a custom tune, and make sure you are running aT LEAST 91 octane (best we can get here in Kenai, AK).
I have the same questions. Best MODS? Opinions?
These are the mods I was considering. I also plan on swapping the cams and deleting the MDS eventually but for now, I want the most torque increase I can get with minimal modification (anyone with experience with any of these mods, please comment. It will answer OP's questions too):
1. Tuner (not sure which) with an unlocked PCM. I am keeping my old PCM just in case. Especially after what happened with the Pulsar. Hemi fever tune
** Any recommendations on the tuner? Anyone have good experience with anything in particular ?
Eventually
2. Fastman throttle body (not necessarily larger, depends even with the cam, I do not think I really need to go up in size unless the MD delete would benefit)
3. Performance Coil pack with larger gap and copper or iridium plugs. (I just hit 57K miles anyway)
Eventually, I would like to do the following:
4. MDS delete kit with Cam and upgraded lifters.
5. Transmission Valve body upgrade.
Its the Tuner that I really want. I loved the Pulsar power and torque response. It just tried to break my truck. I figure with the tune, and open throttlebody and a better coil pack/plug gap would show some real world torque gains. Thoughts?

MBRP 4" high flow exhaust and a AEF high flow air filter.
De-badging it this next week. =]
HP Tuner is the only way to go.
Diablo canned tunes are a joke at best. and Diablo dosent allow you to actually change anything yourself. So you're stuck emailing your tuner for any little tweaks you want to do... Its super lame.
Crap. This was meant to go in the 4th gen section. Need an admin to bump the thread over.There are no options to tune a 2019-2022 Ram with the 6.4. They have not unlocked the PCM yet. No one offers an unlocked PCM for 5th gen 6.4's.
Best we can do is exhaust, throttle body, intake.....but there really are no gains other than how it sounds. Basically yeeting money away for nothing.
Nice!!! Are there different power levels on the pulsar? If so, what level have you been running?Over the weekend I installed the Pulsar and holy crap did it wake up the 6.4! Such an easy install, and updating for tires and axle ratio was a piece of cake. I also did the MBRP single catback exhaust helped the truck breath easier as well. Don't do the CAI as our trucks are already great in this area stock.
