Been following BMW doctor for a while now. He claims he has a tune that can give 272 bhp!! Obviously you'll need the 3 stage intake. I am considering it but can't seem to find anything about his tune on the internet. Does anyone have experience with this tune?

[bluewater328]

He's claiming N53 numbers, IIRC. I think he's a hack and he watches/steals from other contibutors, but that's just my opinion. That said, he knows a few technical references that were helpful if you get past his annoying presentation.

Please stop following and watching this guys videos.

It's rubbish advise and then he charges money to help people fix things.

The n53 is different from an n52 with 3 stage?

How else is he to make a living from fixing cars XD

[hassmaschine]

just.. no.

I'd bet a signed dollar his "tune" is actually just one of the free ones downloaded from Bimmerlabs with the watermarks removed - I couldn't watch it because he had a paywall, but there was a video earlier that he supposedly had tried to flash a 3 stage tune, but could never get it to work because of the power class.

His annoying talking sound like scam. Would like to see dyno though.

Though in this website it states that N52B30O1 (2006 – 2010) were 272bhp:
http://mywikimotors.com/n52b30/

1. N52B30U1 (2004 – 2011) has the following specs: power – 218 HP at 6,100 rpm, 270 Nm of torque at 2,400-4,200 rpm. The power is decreased with the help of new intake manifold and ECU. It was used for BMW models with 25i and 28i index.
2. N52B30M1 (2007 – 2011) is analogue of engine produced for the US market. The specs are as follows: power – 231 HP at 6,500 rpm, 270 Nm of torque at 2,750 rpm. It was used for BMW models with 28i index.
3. N52B30O0 (2004 – 2011) is a basic engine with 3-Stage DISA intake manifold. Power – 258 HP at 6,600 rpm, 300 Nm of torque at 2,550-4,000 rpm. It was used for BMW models with 30i index.
4. N52B30O1 (2006 – 2009) has the following specs: power – 265 HP at 6,600 rpm, 315 Nm of torque at 2,750-4,250 rpm. It was used for BMW models with 30i index.
5. N52B30O1 (2006 – 2010) has the following specs: power – 272 HP at 6,650 rpm, 312 Nm of torque at 2,750 rpm. It was used for BMW models with 30i index as well as in X3 and X5 crossovers.

I agree with what your saying. I used to follow his buddy nathan bmw i think his name was. At first I was in full support because i thought there were in the business of helping people until a few red flags came up. such as they would put down the forums, saying its unreliable info?? (wonder where he got his info??) during there live stream i saw they were pushing really hard selling free diag software for a "limited time" (ista/inpa). I thought that was really fishy because i downloaded all that stuff for free. I called him out on that during there live stream together, when i was ignored they blocked me. i un subcribed and blocked all there content.



Clearly there running a business of brainwashing unsuspecting people.

I think that is inaccurate. For one, they produced the N52 up until 2012-2013 for the X3 and X5, and up to 2015 in the 7 series. There was no 268hp version of this motor in 2006 either.

Wiki also states N52 "200 kW (268 bhp) Applications" engine existence:
https://en.wikipedia.org/wiki/BMW_N52#N52B30
Wiki uses this website information:
https://www.automobile-catalog.com/c...teptronic.html


Where could we find accurate information?

[hassmaschine]

From BMW!

There is a 268hp engine - for the X3, X5, and 3.0si. It just wasn't in 2006. There was never a factory 272hp engine.

And actually, they're all exactly the same engine (block, crank, pistons, head, valves, cams, etc). The only hardware changes are the intake manifold and exhaust, the rest is all in the calibration.

So its the same Bimmerlabs tune for 268hp engine? Just need to use EU air intake, 3 stage intake manifold and wider exhaust?

I went down this road a really long time ago. Way too many people reposting BMW HP values and getting lost between HP vs PS.

I dug through most of these calibration files and there is nothing in them that would produce more power. All the Hi output versions are nearly identical.

Any real gains would be related to better flowing exhaust systems.

Of course the direct injection N53 is a different animal. Fueling and exhaust would be different and I believe the compression ratio is higher. In addition. The N53 was an EU only engine, so it could be calibrated to different emission/fuel standards.

[hassmaschine]

yeah, I wonder if that other wiki was actually talking about the N53, not the N52 - because the basic version is 272hp.

[E92_William]

I think the fact that he quite literally steals Scotty Kilmers video thumbnails should be enough of a red flag.. You could fill a couple pages on this thread just quoting the bs he's said and this is more of it.

He can't make 272hp on an n52 with a 3 stage, if stage fp, bimmerlabs or aa or any of the other known tuners can't, this guy isn't gonna be the one to make it happen after him and his buddy struggled for days to try and convert a 528 and a 328 to the 3 stage with 0 success.

I think the N53 numbers get confused all the time with N52. n53 has 13:1 cr which perfectly explains the 272hp.

Agree with what others have said, stop watching his bad advice. In one of his videos a year or so ago he said not to do the coolant bleed procedure after cooling system work because you could run the pump dry. The only way that would happen is if the system is full of air hahaha.

His buddy Nathan had a similar experience and said the 3SIM doesn't do anything for your car..

I watched one where he preached to never change the transmission fluid because his toaster e60 is still shifting fine and has high miles (obviously the previous owner serviced the thing before) there also a few others claiming to never put headers on cars and I'm sure much more if I paid attention to the channel

I was thinking about the N53 a little more and did you realize that the intake valves are smaller than the N52? Guess they had to make them smaller to make room for the fuel injector. They also dropped the Valvtronic system.

Different cams and cam adjusters for both intake and exhaust.

Hmmmmm.

I've seen Nathans channel. He posts great content ngl. But it seems like he's kinda fed up with BMW... as seen in this video:

Nathan made the mistake of not adding the tune so the 3 stage intake didn't do anything. If I am not mistaken the 3 stage is basically converts a 328 to a 330. Websites claim 272 hp NOT BHP. So I am confused to what this guy is claiming when he says 272 bhp with his tune...cuz that's a big difference...

272 bhp would be amazing. But from what I read online not very possible unless I do FBO, intake, exhaust, tune.
There is also the n54 intake on the n52 that claims 250 bhp?? That seems cool but way too much work.
I'll probably still take on 3SIM project this summer but in the mean time if anyone has any other suggestions for a little more power I am open to it

[hassmaschine]

Just use the Bimmerlabs 328i to 330i flash. It's easy and free, guaranteed the factory 255hp without any BS. And I won't waste 20 minutes of your time in a YouTube video talking a lot, while actually saying absolutely nothing.

LMAO This is so true.

You forgot "looking like you're going to have an aneurism...."
