If I wanted a tune I would go aftermarket, no questions about it. Dinan comes to mind as they appear to be safer from a novice's perspective.

But if the PPK does nothing how do you explain that the 335i without PPK is slower than the S4 and the 335i with PPK (at 20hp) is just as fast as the S4.

The good thing is the PPK test can be done by anyone right now. After work you can get an S4 with auto transmission for a test drive and right afterwards go pick up a 335i without the PPK (odds are that's the only one you will find at the dealer).

Your butt dyno will tell you what you will get with the PPK (old one) after driving the two. We already know what the real dyno tells us about the PPK so you have two frames of reference right there to make up your mind.

The good thing with the PPK is there is an abundance of information (including the test I outlined) that should give anyone a fair sense of what they are getting into.

The extra burble alone is worth the cash. I have also driven both, and there is a large difference between a non tuned N55, and a MPPK N55. I needed it coming from a PPK N54.

I'm sorry for your disappointment.
This a video of my stock 435i after break-in period:

13" to go from 100kmh to 200kmh. A good performance for a 300hp/306ps N55, but I wanted more, because my previous E91 335xi was medium/hard tuned (400hp on dynojet), so I decided to buy the MPPK.

This is the video on the same highway, with the same weather condition, just after fixing the MPPK 335hp/340ps:

11" to go from 100kmh to 200kmh, and I repeated it 3 other times obtaining always the same result. 2" less for me is a fantastic outcome

I'm sorry for your disappointment, but my opinion is that MPPK is not subtle, but at least remarkable.
I'm totally satisfied

Exactly, there is just so much information out there for an informed opinion. If I were to choose between "subtle" and " remarkable" I would go with the latter, in both cases (20hp or 35hp)

Another thing.
You wrote "No change in induction note from the new airbox. If it is there, I haven’t noticed."
I respect your point of view, but it sounds strange, because I noticed a remarkable increase in the intake note!
On the "burbling" side, for me now there are really soft differences between Confort and Sport mode...

Very nice. I had the MPE and JB4 stage 1 on my 2013 328 and was quite happy with that combo. As everybody knows they do not make a MPPK for the N20 so I felt somewhat forced to go that route for a little extra oomph. Before people ask, no I had zero problems with my 328 or the JB4. Just wanted a few more options and obviously like the extra punch of the N55.

I'm not looking to mod the hell out of my car, but it will be nice to add the N55 MPPK/MPE combo and have no warranty concerns at all. Last I'll add some coil-overs and I will have a very poor mans xDrive version of an M3. Which will be a nice compromise for where I live, DD concerns (family guy), but still have a very nice, comfortable and exciting sports sedan when I want it to be. :thump:

Hopefully this isn't too much OP. Sorry in advance if it is.

Good review.

Butt dynos and perception all vary. Ultimately, the only thing that will really tell you how much faster the car is are 1/4-mile trap speeds or 60-130 MPH times. Either test removes much driver error or launch nonsense.

If you're not competing, the ultimate judge is the butt dyno. I couldn't care less what the timer says if I can't feel the difference.

Wait and drive 1000 miles or so. You'll notice a moderate difference. When I first took delivery (ppk pre-installed) the car was no quicker than the stock 435 tester I drove. Even after a few weeks, the power increase was minimally noticeable. Now after 1200 miles and 2 months of driving, there's a substantial increase in power as well as nasty overrun burble from the MPE.

Auf, are you now happy with the MPE? I know you were disappointed once

If you are disappointed with the US MPE, you can't imagine my disappointment with the UE MPE...
As a matter of fact, their code numbers are different and the exhaust sound too...

It seriously got a lot louder. I honestly thought the "muffler packing has to settle" talk was bs. Now it sounds really muscular at start up and accelerating. It's still sleeper at idle

Umm, sure. But if the timer says there is a difference, a difference will be felt. It doesn't necessarily work the other way around.

Looks like auf is happy with his now. Mine only has 400 miles so far but I am happy with it. I wonder why they changed the MPEs between different countries

Glad to hear you are a happy camper. At less than 100 miles I was not happy but at 400 now it's getting deeper. I love it.

The exhaust tips are pretty cool, I have the ones that came on the old MPE, you have the ones on the 435i

I just hit 300 miles on my car and I already like the MPE. Sure its abit loud on startup when it starts out at 1200 but it dies down nicely when the idle speed settles.

Can't wait to hear it under load, WOT approaching 7k RPMs.

[Jparker82]

Still breaking in my 2014 335 with MPPK. I have around 400 miles on it. It has seemed to of woken up a little. But my 2013 335 AH3 seemed much quicker. It was like a Jack rabbit at speed. 60-100+ was simply amazing. I am hoping for the same results in 335.

I am amazed in the difference in ride from 13 to 14. Like a completely different car. More grounded and handles much better. I am sure the loss of the battery in trunk has something to do with that. Along with 403m wheels.

I might consider doing a Dinan mod in the future.

It sounds awesome, the brilliance of the inline 6 shows its stuff

+1 I was about to order the "old" PPK and am not sure about it anymore.

I know I shouldn't expect it to be like using a Cobb Accessport on N54, but with that tune, I didn't have to guess whether or not it was installed

All I'll say is this.....the purpose of my post is to set expectations. If your expectations are set at the front end, there is less chance of disappointment.

Please understand, not for second am I trying to imply that the MPPK is vaporware. What I am trying to convey to folks is that the difference is there, but, mild/subtle.

I think with the passage of time, you will come to appreciate it.

I really appreciate your rational post. If i were still in decision mode, i would much rather you slightly understate it and then get surprised positively. Many of us are looking for opinions like yours.
However, let me play devils advocate...
1. How many miles have you driven with the MPPK installed?
2. When is the last time you had your butt dyno calibrated (its recommended after age 50)?

[MDIVISION]

Some people simply don't know how to drive. There is a very noticeable difference with the MPPK
