I really dig the noise now. We went to see Thor tonight and as we were leaving, I thought to myself, "I love this masculine sound".

Btw TNAdanzig I would definitely be interested in a downpipe. I wish I could get you working on an exhaust for my passat tdi. Do we have to worry about additional programming for converter delete?

There is no effect to performance or longevity with the combustion noise.

Thanks

Sounds good. No additional programming is needed to run the downpipe. I have thought of getting a vw tdi. I have been close a few times on getting one. I think early next year I might end up getting one to play with. Been looking at a A3 TDI. Just wish they came in the Quattro variety.

You will find that adding some TWC 3 2 stroke oil to your fuel will quieten it down again. There are a few threads about it on this forum.
Worked for me.

Cheers, Craig

The tcw3 does quiet it down some. It takes some of the harshness out of it and makes it a little more mellow.

TNA- I have so far enjoyed my new passat tdi. I have had two, the first was a 2004 that got around 38mpg. The new one is averaging 48mpg. I just looked up a German version of the A3 TDI that gets 73.5mpg.

I'm sure there is a market for GDE/TNA with these diesel cars. I haven't found the forum where you can discuss it freely yet. Tdiclub gets all silly when you start talking about deletes.

Ok well I got my DPF deleted today and welded up a delete pipe for it out of 304 stainless, had a mechanic friend of mine rev it up while I was crawling around underneath with a soapy water bottle, all good no leaks. I rodded out the cat was well while I had it all off of there. What a bi*** that was. Oh well its all done now. I did take a good look at where the cat goes up and I don't think it would be to hard if a guy had a couple days to replace that pipe entirely. I do have a question though what does everyone do with their tubing that comes off the DPF? I ziptied the longer one that looked like it would flop around up to the exhaust mount but would like a more permanent solution. I left my resonator in place and am really happy with the sound of the exhaust, its not really loud just kinda more snappy with a bit of a lower note, not sure how to explain it. What I do like is the vehicle response which seems to be much snappier.

Thanks GDE for the great tune and giving me the ability to knock out that dang DPF.

TNADanzig what do you mean by downpipe? Are you talking from the turbo down to the DPF? Or where the DPF would be had I not chopped it out?

I just removed the pipes from the sensor at the top. The pipes are held on with a few 8mm nuts. Easy job.

I did the same when removing mine. I had a little issue with the bracket on the top right next to the frame but it was still pretty easy.

diesel clatter

Yah, I to have noticed it at times under acceleration at lower speeds. If it was a gaser I would say it was detonation.... injection timing a little off? Hard to say? Mostly my Jeep runs great and I would hesitate to fix what ain't broke but there might be room for improvement.

Mine has started that in the last month or so - meaning about the same time as they switched to winter mix fuel... On the first mile or so as it warms up, and only if I lean a little too hard on the go-pedal. And as I had almost 18k miles previous to that without it, I'm wondering if it's the fuel quality as much as anything else.

Uhh no. It's not a nice diesel clatter. It has a very distinct knocking and pinging noise. Coming from gasser engine enthusiasts world, that sound is like nails on chalk to me.

It only seems to happen when the engine is cold and you give it 50% or more throttle. Take it easy first few miles and its good.

With that being said I've been driving with GDE Eco tune for about 5 days and I don't see a major diff. The way some of you were describing it, it was the second coming of Christ.
Sure there is more mid range and I like the fact that the tranny shifts to a higher gear sooner but I'm not seeing a major increase in MPGs. I'm in Canada so this will be in Liters per hundred kilometers.

I usually get between 9.7 and 10.2 L per hundred kilometers before the tune. On my way back from visit to US where i filled up I averaged 8.8 l taking it easy and doing mild drafting and then installed the tune. Since then its slowly creeped up to 9.5l. Maybe it's due to US difference in gas. Apparently Can gets higher cetane. We'll see

Your decrease in fuel economy could be from winter blend diesel. It happen to me when I installed the. DPF delete last November. Was disappointed a bit at first, but looked back over the last few years on my fuel usage spreadsheet (been keeping hand calculated since new) and there was an improvement. Lot better in the summer.

Like I said, I'm not lighting the torch and grabbing the pitchforks just yet. I'm going to refill with regular diesel I run normally and then see. I am def seeing a higher DTE number. I would usually get to 700 and the light would go on. I'm at 700 now and a fair bit off normal fuel guage position.

Is it possible for these tunes to install wrong? Hard to explain what i mean ha, but for my camaro i get custom tunes done on the diablosport trinity and after i install the tune i have to send the last written tune back to him so he can check if it installed correctly. He said sometimes it can go in a bit wrong. I dont know if this could happen but it crossed my mind so i thought i would ask. I to wasnt noticing a mpg increase, in fact i havent seen my jeep get to 9L per 100 since the tune, but it could also be true that they switched to winter blend in really early fall...but who knows.
