There's only one transmission tune.

I had a full delete and tune by Kassel about a month ago/2k miles. Pretty happy with it so far. Fuel consumption is up on the lower end driving around town, up a good bit actually. City only (Philly) less than 30mpg, but highway only, about 45mpg @80 with some drafting in traffic. It'll do about 40 or so with no traffic/no drafting. General feel driving about is that low end throttle was more sensitive. Highway responsiveness is better. Cruising at 80 you just give it a bit of throttle and you doing 100-110 with the only difference being windnoise in the cabin. The tune has definitely made it more sporty. No issues so far. Engine sounds better. There was previously a bit of a rattle between 1500-2500 rpm when giving it a good bit of throttle. Since the work was performed, that rattle has disappeared and the engine sounds much healthier. In addition, you get more turbo sound and better exhaust note. I understand this was just optimization tuning for the deletes. I look forward to going back to Kassel for more work. They have a good team with staff that are knowledgeable and enthusiastic to speak with their potential customers about projects.

Does Kassel have their own tunes or are they just providing service and utilizing other tuners software?

Running the DUDMD Stage 1 tune w/EGR + DEF delete & xHP custom trans tune, very happy with the combo.

I'm looking to move towards the Stage 2 tune which deletes the DPF manifold and replace it with a downpipe. Simultaneously I'd like to upgrade the intercooler with a Wagner EVO II model.

I'd like to retain the catalytic converter to minimize the smell.

1. My question is is there any negatives with deleting the DPF while leaving the catalytic converter in place?
2. Can I leave the non-o2 sensors that are plugged into the cat pipe in place when I delete the DPF?

TIA!

Okay I’m looking at completely deleting my 2014 328d. So my question to everyone is what do I do after deleting it? Obviously it has to be tuned, but by a professional tuner or can I do it myself?

Any advice about anything with my new car would be greatly appreciated!
Also I don’t know how to make a post, so I guess this is a reply?😂

Welcome to the community! I've gone the EGR/DPF/SCR delete route, surprisingly my DPF was exceptionally clean and I probably could have gone much further before deleting. Car definitely smokes more when you lay into it which I'm not happy about. There are benefits to deleting but there are also negatives that come with it too.
But if you have to ask about tuning afterwards, then you’re best off going to a pro who can tune out the deletes ��. I used DUDMD but there are several tuners out there to choose from.

So can you tell me the pros and cons of deleting it?? And what do you mean it smokes more? And where from?

Is anyone running Malone/Tunezilla? A lot of the vw/audi guys swear by Malone tuning and prefer it over kerma. I’ve read better reliability and that their advertised gains are 100% accurate unlike kerma’s and other tuners.

That's an awful lot of "hearsay." Don't waste your time with Malone for this platform. Do you want a tune from someone that daily drives the 328d and has a ton of time getting intimate with the subtle nuances (KermaTDI), or one that probably never even owned one (Malone).

I have a simple dinantronics, but am contemplating getting a really good tune. My priorities are reliability as well as keeping all my emissions equipment in tact. From what I’ve been reading kerma seems like the best option. I surf the Audi/vw tdi boards (my previous diesel was an Audi) and read positive things about Malone so I thought I’d ask and see if anyone had experience.

I’ve read a lot of your posts so thank you for all the insight you’ve given me indirectly. As it’s sits, I’m most likely going to end up with kerma stage 2 in my car.

A real tune will be a world of difference from the Dinan piggyback (which from my own dyno testing on two separate dynos did pretty much nothing)! You're right that the KermaTDI tune has been developed to work in harmony with the existing emissions equipment.

BTW, the tuner who did the KermaTDI tune is also a long time VW diesel Jetta owner. That car has ~340k miles on it now!

Yes I’ve seen a couple posts where you mentioned 10-11whp gains with dinan for 250 spent, the bang for the buck is there, it’s just minimal, and compared to the transformation kerma does for the car….well, it’s not really comparable.

Dinan was kind of a stop gap for me, slight increase in power while I research and figure out what the best option is moving forward. So I have no regrets with it. I knew what I was getting going in.

How much smoke do you get?

I'm fully tuned. I've driven behind my 328d and there is a tiny amount when stepping on it, but it's barely noticeable. Nothing you'd be able to notice in the rearview.

Anyway, I've been modded for like 30k miles (just rolled over 200k this week!) and I'm very happy with it. My only comment is that while yes, it's got tons of power, it's still a clattery tiny diesel. I haven't put the thing in sport mode in like 2 years. Modding is still 100% worth it for the reliability improvements and it really does drive a lot more smoothly for normal day to day use.

Who would you recommend for getting a real tune? Kerma isn’t going to be an option for me unfortunately.

I have a Malone tune on my TDI but seems they aren’t the best option for the 328d

How come Kerma isn't going to work for you?

Kerma TDI stage 1 for me. 142k miles, added something like 3k ago.

I wanted to keep emissions equipment and this made a lot of sense. As others have reported, DEF usage does seems much higher even in my limited mileage.

Its a great balance though. Punchy, strong pull at the top end and though the stage 1 doesnt include a transmission tune (IIRC), it seems to have changed slightly and is smoother and holds gears better than before.

I cant comment on the MPG though. Months of limp mode triggered and constantly looking for any evidence on why, I replaced a bunch of sensors, boost pipes and it seemed to have been the MAF! Replaced that and MPG shot up. Cannot isolate between the tune and the MAF though. Getting solid numbers though, so can say that its certainly not dropped!

One fairly steady run on 55MPH country roads was showing 625 miles range and a solid 48MPG overall. Got to go modern Prius to get better!

[rparnel1]

I also have a Kerma stage 1 on my 2014 328d with 120K miles. Have had the tune about 4 years. Can confirm that the DEF usage almost doubled after installing the tune. However, performance and driveability seem like they almost doubled also!

Question for those with the Kerma transmission tune. When shifting manually (or in auto to I guess), are your shifts from 2nd->3rd delayed compared to 3-4 or 4+5? By delayed I meant a higher minimum RPM before the car will let you shift. I usually shift manually and found that the shift from 2nd to 3rd can't happen until around 1700 rpm, where as all other up shifts are allowed at a lower RPM...

I am also interested in this. I would like to go to a full delete and tune but more concerned with EGR delete and tune for the longevity of the motor.

Kerma is by far the most refined tune from all the research I have done, It seems as he daily drives one he has refined it the most and has seen customer dyno charts to show the claims on power added. I would love to get his stage 2 tune and trans tune but I know due to EPA crackdowns there is no option for delete.

Does anyone know if there is a possiblility to get an offroad/track waiver for the Kerma tune to be able to have stage 2 tune with deletes?
