2025 Ram 1500 Current Owners - Discussion, Feedback, and Problems

[RamTruckMan]

In regards to the power increases, that’s running E85 fuel. Power gains for 91 octane are much more modest. Having said that, I bought said tuner and it is noticeably peppier in everyday driving. I have no plans to run 93, e30, or e85 to really take advantage of the tuner.

Screen replaced yet?

Agree 100%

Yeah, but…unless the fix is something that can be fixed OTA… they’re only gonna issue a TSB (which the major population is unaware of, yes, we’re geeks) and it’ll only get fixed if A. A person go to the dealership and B. The dealer is competent enough to look it up.

100% agree

@Jimmy07 would be very good for input on this.
My totally uneducated guess would be they would keep the new Atlantis architecture, and modify interface modules as needed.

The 2026 hemi will be on the Atlantis architecture

I think this is where the engineers said it would take over a year, and Kuniskis pushed, and they did it in 6 months or something much less than planned (which *might* be cause for concern).

I think they purposely said that, knowing it wouldn’t take long at all, to frame themselves as “heroes” to us for adapting it so quick. The PCM is the only thing that needed to be programmed for new architecture, but this has already long been done, being that the 2022 wagoneer used the 5.7 hemi on the Atlantis architecture. So all they really had to do was tweak the engine calibration.

All I run is 93, I may need to consider this....did you run in to any issues installing the tuner?

Speaking of dyno numbers, these are nuts for a factory truck..

dyno recording 461.2 horsepower and 484.1 lb-ft at the wheels

That's pushing 26psi too. I'll stick with my 8-9psi and after 5 reliable and easy to work on Hemi's, I'll keep what I built.

Seems peeps keep trying to justify their little 6 cylinder overboosted engines. No doubt they are powerful for a little motor. Maybe they will prove to be decent engines, but still no replacement for displacement.

Orrrr.... did "they" say that because "they" didn't want to do it at all? But, the boss overruled them and said "make it happen" and then it miraculously didn't take that long?

Doesn't a stock SST HO make more torque at every RPM than a stock 5.7 Hemi?

If so, that seems like a 100% replacement for displacement...

Clearly there is a replacement

Nope. Part still on back order with no eta. But don’t worry, it has an “expedited” request. Whatever the F that means. I asked why they can’t just take a part from the assembly line and they said they are “different parts from different manufacturers.” I don’t know anymore. They offered to extend my warranty once I do get this fixed so we will see how that unfolds.

That could be cool if it’s a blanket extension. Not that a radio extension would be bad but…

nope. It was very straightforward and easy.

so just for fun I loaded map two, which is supposed to be for 93 octane and above. I did a non-boosted four-wheel-drive start and this is how I would characterize it:
The engine is sadly slow until the turbos spool and once they spool this thing kicks! Holy cap did it take off like a rocket. doing a boosted four-wheel-drive launch would be something to experience.

 

[Riding Deacon]

By any chance, does the JB4 tuner have the capability to disable the auto on/off start feature?

Sorry for the late response here Fred....I don't always log on...but as far as I know it does NOT.

I don’t see any options in the app to disable the auto start stop.

Okay, Boomer

 

[LOWRMPG]

Okay, Boomer

While I wouldn't reserve it for just Boomers, there are plenty that think it is still 1999 and those "Fast and the Furious" kids are out of their minds.

Did you go with the paid mobile app?

 

[RamTruckMan]

Okay, Boomer

Pretty sure he’s Gen-X, like the both of us…

 

[USMUSL]

Yet his perspective is not. Perhaps we should all use non-ethanol fuel and change our oil every three thousand miles also.

LOL, all in good fun.

I’d rather do leaded

I got the Pro adapter that uses the free app. I have no knowledge on what can be done with the Mobile adapter and the paid app.
