Any 09 people have/want a dpf delete?

[Mark@MaloneTuning]

Looking at the graph for the Malone tune all the power is at 2100 to 2300 rpm. It then drops off fairly quick.

The one Here
I believe it's the same one on your site.

That dyno does not show the power dropping off after 2300 RPM. It builds all the way to around 3800 RPM and it does not drop off steeply until around 4400 RPM. It varies - if you're in a hot climate like in TX or if you have a very aggressive tune where you'll hit the EGT limit earlier, you may see the power curve drop off a bit earlier.

What you were probably referring to is the torque curve, not the horsepower curve. Yes, the torque starts to drop off at 2300+ RPM and that is very typical of TDIs. We could lower the peak torque so the torque curve will appear flatter on paper. Its peak could extend to 3000+ RPM.. but then you'll have less torque.

Jeez, does that stage II graph include the DPF delete?

I absolutely do not need to spend an extra $50 on the stage II tune and $750 plus install on the DPF just for 10 hp and 8 more ft/lbs over what the stage I reflash gives you...

That's easily over $1000 for astoundingly minimal gains vs the stage I

That Stage 2 dyno result was taken WITH DPF. The only modification was the Stage 2 tune, nothing else. This is the dyno video where this Stage 2 graph is based from: http://www.youtube.com/watch?v=gULtk0b4vRA

Deleting DPF is not necessarily for more power, it's an alternative to an expensive DPF replacement or for those who want to gain 4-6 MPG.

Fuel millage and extra power are a plus.

Im looking at this from a preventive maintenance point of view as well.

If the turbo and motor can breath a little easier then this should prolong their life span.

Not that I won't try and spank some ones ass from stop light to stop light while there thing my little diesel is a turd.

My car only has 9800 miles on the clock. I don't turn vehicles over very often so im looking for this to last many years down the road.

Cant see much extra performance on paper with the stage two tune. Am I wrong?

I'm going to do the DSG tune as well.

My bad with the initial Power loss question. My brain malfunctioned and was reading th white doted line and the solid white line as HP and Torque

Totally agreed. That's exactly why i'm doing it. Lower EGTs are a huge plus too.

That's what I thought. Lower EGTs and backpressure will definatly have a good effect on that, but I spoke to my old diesel teacher (a diesel engineering genious imo) recently and he mentioned lower backpressure can be a double edged sword. He brought up the possibility of overspeeding the turbo to the point where the fluid bearing of oil breaks down due to lower backpressure causing it to spool way quicker than stock. He said by the time the wastegate kicks in it will already be spinning down from the overspeed, and the damage will be done.

It also occured to me that maybe the VGT vanes could correct this problem through correct tuning, but im not sure on that one. Just food for thought.

Dank,

Note that is why we use 2.5" piping and give the VNT system some back pressure to operate. It allows the tuners to easily compensate for the extra flow without being overly aggressive for the turbo and turbo control system. If you go too large you end up having the turbo boost creep and then fueling and boost request must be tuned back. This reduces low end rpm hp and torque where the diesel shines and gets better fuel economy.

[Subaruski1]

Shorty what is this for?



And can you explain the pros and cons of an EGR delete?

[1972SS454]

^The above pictured part deletes the HP EGR valve that is bolted between the anti-shudder valve and intake manifold (pictured below). The HP EGR delete kit also includes a block off plate for where the pipe runs off the exhaust manifold. The HP EGR system is not filtered like the LP EGR system is, so it recirculates crud back into the intake. When i removed mine there was a solid 1/8 inch coating of crud on the valve and in the intake manifold. You can see the valve is also quite restrictive, so there was a notable change in responsiveness once it was removed. Optional tapped holes in the delete pipe can be used for boost gauge, water methanol injection, etc.

The only Cons are that you are removing emissions equipment. Also, possibility of slightly decreased fuel mileage. Will also need ECU tuned for EGR removal.

[Subaruski1]

APR has release their CR tune, $500 currently.

[shortysclimbin]

Interesting.. I wonder how long the DPF will last with that much increase on a stock setup.. Others have had issues with aggressive tunes 40k miles down the road.. I hope others don't end up like this with APR.

Some other things to note is the power and torque on that thing are really lumpy. So far the downpipes and stage 2 tuning has proven great reliability, fuel economy and a nice fat powerband. with LOTS of mileage on them.. We will see what that APR tune puts outs and compares as its not all in just the end number..

EDIT just noticed they are looking at block power not wheel power.. Silly me.. they should be ok as that is not too aggressive. stage 2 is still a lot more power output.

[PDI]

I think you mean brake not block....

[matt_g]

My car just crapped out on me yesterday morning so I am trying to hunt down a down pipe and mid pipe now

Crapped out how? Clogged dpf?

Diesel performance and rawtek have downpipes I would recommend diesel performance talk to Kyle he was extremely helpful with mine

[matt_g]

Got mine from rawtek yesterday

[GoldenNugget]

This is diesel performances Downpipe egr delete and kyle's cat back comes with the mid pipe as well ... looks like that resonator is massive on rawteks is it ?

[matt_g]

Yeah it's pretty hefty. Haha. Built really really well though

[GoldenNugget]

That's all that matters haha

[dhimarko]

GoldenNugget, how much did the egr delete and downpipe cost with the cat back and mid pipe

[boostin20]

Golden nugget, isn't that stuff you posted for a mk5?

Around 2200 with a stage two custom tune I'm putting it on the dyno on wednesday I'll post results. I had the stage one apr tune with everything else stock and I was seeing around 168 Hp and 274 tq

[GoldenNugget]

Yeah it's for a 2.0 but Kyle has stuff for any of the tdi engines

WOW! I might just have to use that as an excuse to buy my downpipe now...

What's up with those cams Kyle? CR?

Dyno results I switched from apr to the stage two malone with kyle's full exhaust and a CAI.
factory 131hp and 194tq

Do you happen to have the torque graph???

I do somewhere on a jump drive haha I'll find them and try to get them posted I'll also throw a link up from the video of my car on the dyno as well

I'm still not understanding why people waste their time on a company (like apr...) that hasn't invested in diesel technology in years.

Keep in mind he still had the dpf installed with the apr tune...

Thats very true...

Even the curve looks better w/ the malone tune. I'm interested in seeing torque also.

[GoldenNugget]

I'll look tonight when I get home ... I think Malone is way better to work with then apr as well I have called and talked to Kyle and Mark Malone and they get right back to me good guys and if you tell them what you're looking for they will put you on the right direction and not try to sell you extra bs you don't need and spend money you don't have.

As far as the tune itself goes I jumped on apr bs there is a dealer near my house and I was excited to tune my 2.0 so I bit and had it put in. Then come to find out that was as far as you could take the tuning and car they don't offer any custom tunes either. My check engine light was on for months even before I got the tune Bc of the LP egr valve. The dealer switched it out a few times I got a new dpf cat and Flapper and problem was still there. I called talked to Kyle explained what was going on. I bought the exhaust and tune car is perfect check engine light has been off since h20 and car runs perfect and has a ton of pull compared to stock and I've been averaging about 53mpg driving all week going to h20 I got about 57 which is way better then my 41mpg. Very pleased over all and I def recommend these two guys over apr any day.

Yes it does. I would like to know what's up with that dip in power at 75mph with the apr tune. HP vs speed doesn't really tell you too much. I would like to see HP and torque vs rpm to get a definitive answer on that.
