Thank you for your review. I’m glad to hear you like it.
pretty much any tune is better than stock. Seems like there is a lot of hair splitting over tunes.
I appreciate your honest review. I don’t know what my top speed is, I’ll have to try that in Montana. It’s too mountainous here.
I have an HDDS tune and am happy with it as well.
I’ve heard a lot of complaints about buggy tunes. I won’t mention any names.
 
I sure hope this gets updated to help warn others. I have screenshots of WAY too many customer's of Randy's trying to get their truck fixed after switching to his tuning. The guy is a hack that has no business messing with computers.
 
Loll, you should see the recent review on facebook page, it's horrible what he has done, he's a scammer.

TUNING POST: sorry it is long. This week on 12/20/21 I had my truck tuned by Randy and Ecodiesel Performance USA. I paid $2300 for a stage 2 tune, transmission tune, secondary ECM to be tuned to leave my factory computer stock in the event I return to stock someday, a downpipe, and mid-pipe to rear axle. The downpipe was a gen-4 ram ED pipe that his shop guy cut and butt-welded on site after fitting to the truck. Prior to my tune, I asked if I should purchase EOC exhaust from their website and have shipped because the quality looked excellent in my opinion. ecodieselUSA told me that their website says they never have them in stock and they have to custom make them and it would take months to receive one and the one he could make would be better. I passively took his word and proceeded to schedule my appointment to tune the truck and sent payment on his website. I drove 2 hours from home and arrived at my appointment for my tune at 12 noon when I was told they would be ready for me but there was another customer there having their vehicle worked on until approximately 3pm. The computer was flashed during the downtime, and then the emissions components were removed and the work was completed at around 8:45pm. Throughout the wait of my visit the shop had less than favorable conditions for a customer to be waiting on site at, just a hobbyist garage, with a small propane heater, a non usable bathroom and no seating, which is fine. Just know that if you intend to wait there for a tune and delete. After the work was performed, I got in my truck and left and started on my 2 hour drive home. Immediately I noticed increased power, HOWEVER; several operability issues related to the tune.
1. While accelerating, trans slip in multiple gears. Boost increasing, while transmission staying in the same gear and engine revving while speed not changing at a fast enough rate to keep up with RPM. Should have down shifted.
2. Engine sputtering under very heavy acceleration, almost as if choking and and wanting to stall, like it needed to clean out but couldn’t.
3. Engine sputtering and chugging like it’s going to stall under very light pedal pressure while accelerating at approximately 1650-1800rpm in all gears. (Felt like traction control was kicking in but wasn’t)
4. At highway speed 72-80mph with cruise control set, in 8th gear boost would continually build and drop build and drop build and drop over and over and over on a flat level highway with no load condition. You could hear turbo flutter every 5 seconds and the wastegate or diverter flutter and watch the boost drop and the truck would dramatically slow, and then race to catch back up to set cruise speed.
5. I turned cruise control OFF and situation number 4 still existed with a steady foot.
6. There was a considerable amount of black smoke in my mirror behind me in the dark, dimming headlights of cars behind me.
7. When slowing down, the transmission would shift hard into 2nd and 1st before starting again from a stop.
THAT NIGHT I GOT HOME
I messaged ecodieselUSA and expressed my concerns and he said he has a new file for me ready to go. We worked it out so he went to the post office the next day around 1pm and overnighted me another PCM to swap into my truck with an updated file and that I should report back to him.
I waited until Wednesday when I got home from work to swap in the new computer and went and drove it 100 miles. Honestly, I didn’t know which tuning file was worse. A lot of the same symptoms, same issues, same disappointment. I had a long trip for the holidays this weekend and I told him I need the bugs worked out so I can confidently drive 400+ miles with my family.
THURSDAY NIGHT came around and I got in my truck and drove another hour and a half to meet him to get yet another PCM with another tune file that he said he made 1000+ changes to, including adding boost, changing the vane position, etc. this is all foreign language to me so whatever, I don’t know the difference between installing a potato where my computer goes, or the actual fucking computer. We meet halfway on site at a gas station, I give him back the other 2 PCMs with the bad tunes that don’t work and he installs the 3rd PCM that he says will be fixed and have amazing drivability characteristics and be much much better.
I leave and I’m on my way.
A LOT OF THE SAME ISSUES. A lot of the chugging and stalling feelings at certain RPMS have been lessened but are still prevalent but more accentuated in smaller bands of RPM ranges. The turbo flutter and diverter blowoff sound is MUCH MORE FREQUENT and worse, the truck shifts worse, my wife instantly got in and within 2 minutes of riding asked what the **** is wrong with my truck. So I had to explain. This evening while we were driving to my family’s house, the truck stalled on me going about 30mph and we coasted to a stop. Everyone was wondering WTF was going on. Nothing feels as shitty as that on Xmas eve driving with your wife and 3 kids in your brand new 2021 truck. This was the last straw for me. I’m not going to attempt to have the tune fixed by ecodieselUSA, as I don’t feel it is objectively something that can be done with the precision and accuracy that I demand out of my truck. I can’t afford any more time or effort invested in testing, and while I thought I would try to work through it with him, I need to do what is best for me and the protect the massive amount of money I have spent on this vehicle. I suggest doing your due diligence in really paying attention to what people are saying around here. I made my decision to tune with ecodieselUSA simply due to the fact that he was hours away from my house and could perform the work and have his hired shop guy do the exhaust removal at the cost of $400 cash on top of the $2300 I paid online. It was simply convenience. Sometimes convenience is not the best option.

Ok, her it goes...

After running the engine tune for a while, I kept noticing a couple of different noises when shifting or letting off the throttle. I contacted Randy and he said it was turbo flutter and would not hurt anything. I did some research and most of the information I found said that this is not good for the turbo. It was hard to record driving but to give you an idea, I recorded this just revving the engine from standstill.


I contacted a different tuner and he told me to check turbo boost driving a steady speed on to see what the boost was doing. Boost was all over the place and not steady. Martin (MR Tuning) told me that was rough on the turbo and at that time I decided not to run this tune in my expensive truck, especially since I no longer have any warranty, most probably, with this delete tune. Here are a couple of videos about the turbo surge at a steady speed.



I sent the ECU to Martin and am awaiting its return. Will report on how it does later.

In summary on the engine tune, I cannot recommend this tune. I feel it is rough on the turbo and just not a smooth tune. The tune did give the truck more power and the speed limiter was removed. Martin may can explain more about the details but not a good experience with EcodieselUSA tune. Transmission tune review to follow.

In last 2 videos, is that a distant turbo flutter that can be heard? Seems like it coincides with boost drops...

That sucks, hopefully you could get money back, not just having to pay for an expensive lesson...

On the transmission tune, I received it several days later than the engine tune. It is very expensive because you have to buy an HP Tuner device with credits to access your truck, plus another device to go around the security. Not any instructions and rather difficult to do for a novice the first time. Best to do the trans tune at night and let the truck sit over night for the can bus to reacquire all the devices in the truck like the seat adjustment, a/c, air suspension etc. Things go kinda haywire after disconnecting the security device and takes a while to go back to normal.
First thing I noticed was the truck was holding 3rd and 4th gears at a low steady speed and running over 2000 rpms. Also, in 8th gear anything over 2100 rpms the truck would not downshift at all full throttle. Two videos of that here.



I contacted Randy and sent these videos to him. He was busy at the time but did show me how to adjust the shift points in the program. I made 7 different tunes trying different settings and got it a lot better but still not perfect. I ended up going back to the stock transmission tune. The stock tune did a lot better with the engine tune he sent than with the stock factory engine tune. It would hold 8th gear much better after the truck had more power.

I cannot recommend the transmission tune either
 
Oldsouth,
Thanks for your reviews. I have the SFT stage 1 tunes and I'm in the process of changing tuners. I've been advised to not use Randy for a variety of reasons. Your reports have convinced me to follow the advice. Now I have it boiled down to HDDS or MRT. Currently leaning to MRT.
 
Yep, turbo surge can snap the turbo shaft, oil pressure will then bypass directly into the intake and the engine will do a runaway burning its own oil, there is several video on youtube about this, and the turbo surge on this tune is massive. The boost being all over the place with this tune and creeping all the way up to 30psi while cruising gently is due to several major issue in the tune, it's not a simple fix. A major concern we also saw in the tune is that all the fault codes (1840 fault codes in that software version), all have been completely disabled, it's a shame, if something breaks, no one will never know, and no garage, no dealer, no one will be able to repair this vehicule as there is no more check engine. All the safety limiter completely disabled. Both LP and HP EGR function full active, all DPF functionality full active, but the truck is full delte lolll.... welll...

From what you sent me, the torque converter lock-up function is disabled almost everytime in your trans tune, you will burn your trans if you continue driving with it.

Have you seen the SOTF tune? Several different tunes on the same ECM, uses the DEF gauge to indicate which power level. It has peaked my interest.

Yes, He posted that back in March, makes a guy drool, but requires sending in the ECU. Since I've had the handheld tune device and able to easily change back to stock or replace tunes, I'm spoiled. Not interested in pulling ECUs anymore.

Sending in the ecm is not required for all 3rd gen tuning but I dont think its required for 2nd gen even with Soft.

So if I'm understanding you correctly, on my 2018 Ram I have to pull the ECM and send it to EOC to be able to get their tune?
I was under the impression that they used the handheld to do their tunes.

You don't. The second gen uses the handheld for the standard tunes. I have no knowledge of what the SOTF requires. If the SOTF can be pushed via the handheld, I am a buyer for sure.
