My F30 2013 335i N55 comes with M-Performance power kit.

Does it mean that I have 20hp more with tuning in DME and have forged internals.🤔

Yeah, it makes a few extra hp over stock.

It may have a few extra hp, but it’s a pneumatic waste gate turbo (PWG) so it’s potential is limited without running E85 or upgrading the turbo.

Sorry for being so dumb but what’s the difference between PWG or EWG?

Still a nice kit! While it doesn’t make much sense to buy if you’re looking for a tune these days, getting a car with it is still a nice find, I think you should have the performance intake and exhaust, check under your bumper and see if there’s an ///M on the muffler- a pretty desirable part for most that want an upgrade but not a crazy loud aftermarket system. The tune is fine, you can always get an aftermarket one that pushes the engine more but nothing wrong with the m performance one and I’d be pretty happy if my car had been outfitted with one

PWG and EWG are different kinds of wastegates on the n55 engine, EWG was an updated version that was electronically controlled, but more importantly there was a revised turbo that was a bit bigger as well. Stock for stock not a huge difference, EWG will get a little more gains in aftermarket tunes and has a slightly higher ceiling that can be pushed on the stock turbo. PWG still has plenty to give though- for most people difference won’t matter or be that apparent. Someone who is more familiar with EWG can chime in but unless you’re planning a rather large build you probably wont notice much of a difference.

Awesome 👏🏽 explanation!

And yes I have Mperformance muffler and Mperformance exhaust tips plus the Mperformance sign coming up on instrument cluster when switch on/off..

You are getting some incorrect information. The BMW M Performance Power Kit is a BMW aftermarket kit for F30/F32 335i/435i. It has nothing to do with engine internals or wastegates.

It primarily replaces the bottom of the airfilter box with one that has an extra air hole trimmed in red plastic for effect. It mostly lets out more of the turbo sound from the engine. It has a bunch of decals and a new fancy plastic engine cover.

If you want a small performance bump, then replace the stock airfilter with a free flow washable/reusable aFe Pro Dry airfilter. See photo for part number.

Anyone with a stock intake can obtain the same effect without the decals by either buying and replacing the bottom of the stock airfilter box or cutting holes in the stock unit. Please see photos.

There are a couple different MPPK kits depending on the build date of the car. Some come with an MPPK tune installed by the dealer. It’s a really small performance bump, not worth the price at all. Much better to install a real tune like a Bootmod3 Stage1. (Never install a tune on an F30 N55 without first upgrading the charge pipe because the stock CP is a poor design that will break)

Note: Answer to a common question…
If a tune such as Bootmod3 is installed to an engine that has a BMW MPPK tune, it does NOT add to it. Bootmod3 saves the MPPK tune as the original tune that can be reinstalled at any time. Then it erases the MPPK tune from the car and installs a fresh copy of Bootmod3.

Here is a link to the MPPK kit for your car.

The difference when tuned is more than a little. 50whp isn't anything to sneeze at, but you can still make serious power with a PWG turbo:

My car came with the MPPK tune. No way do I believe that it was 50hp over stock. I have something from BMW saying that the gain is somewhere in the +20’s.

It was nice feeling that with the MPPK tune there was a little more power than the exact same 335ix’s that I had driven that had only the stock tune. When I installed Bootmod3 Stage1 (rated at 70hp more), now that was a real kick in the pants. If the MPPK tune really was +50hp, then the +20hp more from Bootmod3 would have felt relatively minor.

I would only believe a dyno if actually did the same car back to back first with the stock tune and then with the MPPK tune. This was one of the things that I had wanted to test. When I thought that I had local access to a AWD Dynojet, I put a test plan together.

Halim sent me a stock tune so I could use it as a baseline on the dyno. Then I’d work my way up through MPPK, BM3 Stage1 93 all the way through full E85 tune. I was going to test a few components too like maybe stock intake, MPPK Intake (with aFe filter) and MST Intake.

However local AWD Dynojet access was not to be, or I would have great accurate incremental data on tuning steps with the stock N55 EWG turbo.

I have leads on two AWD Dynojets that are more of a drive. They are used for internal product development use, but I’m hoping that one will allow me to test.

It's not 50whp stock for stock - it's tuned vs tuned.

One of you guys is talking about tunes (MPPK vs BM3) and the other guys is talking about turbos (PWG vs EWG)

The rule of thump that I recall is that if you tune an N55 PWG and an N55 EWG the same way, that the extra capacity of the EWG equates to about a 30hp advantage over the PWG. That seems to hold pretty true. As I’ve been modding my EWG, at each step a PWG seems to be about 30hp less.

Check the thread I posted - it can be larger than 50whp closer to redline

Yep.. 600 to 700rpm of usable power band and way more power.

It’s important to note: this isn’t because of the wastegate, it because when they changed to the EWG they also made a change to the compressor wheel of the turbo.

(Although the EWG does allow for more precise tuning of the wastegate, and generally has more support which also contributes to a difference on car’s with the same turbo, like the Pure 500. Just not as significant)
