JB4 Tuner for 2025+ RAM 1500 3.0L I6 Hurricane Twin Turbo (BETA)

[lazerbeak]

I wouldn’t be surprised if Ram comes out with their own tune similar to what Ford did. Factory mod that will be warranty compliant if they do. Hold tight would be my thoughts. Especially with newness of everything in this 1500 platform. Mine is in shop right now and I bet some flashing will be involved to fix it.

Tim is back in charge. Sure they’ll have something for us performance nerds.

^^^This.

RAM would be smart to do this & cash in on what some of the aftermarket will take.

HO Hurricane seems to leave plenty on the table with stock/OEM tune. Kinda like BMW with how underrated their B/S59 inline six turbo motors are & potential for mods. The HO Hurricane is a BMW M2/3/4 motor for the masses!

I would think some dealers would do a JB4 install, just totally depends on the dealership. Or, better to have your trusted independent tech/mechanic do the install & keep away from documentation to RAM that your truck is modified.

Like I've said in other threads, JB4/Burgertuning is a trusted platform going strong for years in the BMW community. It's wise to be cautious with any mod, do your research, but this is a product I look forward to trying on my RHO if I ever get it!

The Mopar performance engineer at SEMA last month told me that they we going to offer a programmer that would be under the factory warranty. Motor reliable up to 700 hp no problem. Said he would beef up the tranny though.

Had a 19 Ram with 8HP75 that was behind a built 426 pushing ~800hp (fuel pumps were my last upgrade to get motor over 1000hp but sold truck before installed). Truck was a monster and did some 2wd and 4wd pulls. Trans never skipped a beat over 20k miles with motor. Its important to program the trans to increase line pressure and shift points up/down to prevent burning up the clutch packs. Strength wise I think the stock trans will hold unless you put slicks on and track it. There needs to be a weakest link and it should be the tires.

Did you have e a trans tuner? I have a bmw 340i with a zf, i have xhp which tunes the tcu, not only increase line pressure, but does a great job with shifting speed, smoothness and a ton of different configurable options.

PCM and TCM both tuned by a local well know tuner (whom I'd never use again). They used HP Tuners software. I ended up taking HP's course, did a bunch of research on HP Tuners website/forum and was able to fine tune the drivability of the truck through data logging, driving, making small changes, etc. However, I've been around engines for 40+ years and old school. I have the knowledge but needed to learn PCM tuning which by the way is very complex. Also need a dyno to realize gains/loses when tuning which I don't have access to thus the tuner dude. They did the dyno tune for performance (timing, fuel maps, etc) for WOT but I fine tuned the around town stuff (closed loop) which takes a huge amount of seat time they didn't want to do. Since this was a unique build there was no box tune available (unlike doing a simple pully and injector upgrade on a stock hellcat motor). Those are a dime a dozen. The best way to tune is through the PCM/TCM and not use a pressure box like JB4. Unlock the PCM and tune it right. My opinion but each their own.

EDIT: One thing I've learned being around some widely tuned vehicles, speaking with reputable tuners, etc is always tune using the PCM/TCM and go with a tuner that ONLY tunes that particular brand (GM, Ford, Dodge, etc). When they specialize in a specific brand they become very knowledge learning that software/motor and what works & what doesn't. Any tuner that does all brands is a dead giveaway to be a generic tuner IMO. having full access offers the ability to modify all the tables for cam position (intake and exhaust for the 3.0 unlike hemi v8 being on one stick), driving modes, driving styles.....just so many variables. I'm also wondering if the 3.0 is already pushing the limits running 28psi. I know the lower rotating assembly is forged and pistons are good for the cylinder pressures, but how much more can it take in stock form? I certainly don't want to flip the bill finding out the limits. My guess there will be another version of the 3.0 similar to the ST and HO motors with different internals, larger turbo, etc that can push higher boost and HP/TQ levels. I do like the concept of the straight 6 and separate intake/exhaust cams for positioning. Makes for a great daily driver (high TQ at lower RPMs) yet scream in the higher RPM range. If they make a small v8 with cam-in-head with possible reverse flow heads keeping turbo inside V....damn. they would dominate. So much parasitic lost having to spin a supercharger unlike a turbo setup. I'm excited to see where Tim takes Ram in the next few years, but I digress. Where is my RHO!?!?!?!? LOL

Yeah, good advice. thanks

Anybody know if this JB4 Tuner (says 104 wheel HP on a completely stock RAM 1500 on pump gas) Is this a safe option? Feeling excited, just got message from Mark Dodge that my RHO is ready in 14 days for pickup.

It’s legit.

BEWARE. Tunes and PCM mods are a minefield of risk. The performance market doesn't talk about it and will downplay it when asked because it directly impacts their bottom line. But hurt an engine and/or void a warranty and watch how quickly the tuners and chip manufacturers are 'too busy' to return your phone calls. It is ABSOLUTELY a trap if you don't know what you're doing so beware.

RAM in particular is difficult to tune and mod because of the Chrysler Neural Network. Inside the computer there are so many checks and re-checks and interdependent variables that it is VERY difficult to modify. It is so elaborate and guarded against modification that tuners call it ‘AI’ even though it’s not actually AI. Torque Management is the big safeguard against aftermarket mods in the RAM computer. Whether technically sound or not, if your truck makes more torque than it should in factory condition, Torque Management will interpret it as a mechanical problem, throw a series of error codes and put the PCM into ‘limp mode’, which means you can drive it but only at 5% of normal operations. It will literally LIMP down the road to allow you to get to a service center.

Limp mode can be cleared with tuners and scan tools but the error codes associated with torque management exceptions are permanently flashed or ‘burned’ into the EEPROM. IT CANNOT BE UNDONE. When you bring the truck in for service, even if it’s a computer update associated with a recall and unrelated to mods, Chrysler will flag the torque management error and immediately void the entire vehicle warranty.

Furthermore, you can’t replace the entire truck computer to get rid of evidence of the error code. Each PCM has a globally unique identifier. Chrysler knows when the computer has been replaced and that is grounds for voiding warranty as well.

If you mod your truck and it goes into limp mode, you should go into limp mode too, because you done screwed yourself. And your aftermarket tuner is going to turn to stone.

Imagine how many Hellcat / TRX owners have asses that whistle when they walk because they learned these facts THE HARD WAY.

I think the best advice for anyone looking into tuning is that you have to be willing to risk your warranty for it. If you're ok with that then go for it.

 

[NDanecker]

when you tune you become your own warranty station.

 

[NDanecker]

Its an ST motor but shows how simple the install is. I still won't do this but FYI for others. I'm holding out for HP Tuners and local tuner to hook me up right.

You're bringing me down.

I installed my new JB4 piggy back tuner yesterday on my 2025 Ram 1500 Limited with HO Hurricane I6. Here is a link to the install video.

 

[bshelton14]

I was able to put the JB4 through some test runs along with a road trip. Here is a link to the video I made with my first impressions along with some live 0-60 runs.

@AnthonyRI does the dealership fill up the gas tank with 91?
