That's correct. I had MPPSK before getting Stage 1 93 and it's a night and day difference. It's not just the bump in hp/tq, it's the powerband and where everything hits.

hmmm it seems I have to upgrade MPPSK.

So which tuner do you recommend guys and why ? MHD, BM3, Mission Performance ?

MPPSK isn't going to have these gains. Maybe half. And I was using Shell 93 VPower.

I recommend BM3 because they have the widest number of users on our platform and records continue to be set with their software. Customer support is very good and they continue to add options and features which is nice. The B58 tunes have been out since April and they've already revised maps 3-4 times, introduced new maps for various user requests (including free MPPSK map to help users learn how to tune) and they have some innovation in the works for wireless compatibility. Even if you're someone like me that just wants a simple OTS Stage 1 tune, it works great.

That being said, I haven't tried any of the others and pretty much everyone that uses other ones enjoys it. There have been a few that switched between MHD and BM3 for various reasons though.

BM3 is the way to go.

Finally took the plunge and flashed BM3 stage 1 91 oct. Just filled up with 94 octane so going to switch to Stg1 93 octane.

I read something a while ago where some people who throw their car on the dyno and it would make less than what they stated (for example, 300 crank hp and it only made 200whp so less than crank) and they sued for false advertising and not getting what they stated for power.

I bought a new Yamaha R6 in 2006 and they offered a buyback because it was advertised to redline at 17,500. The tach was "optimistic" and it actually hit the rev limiter at 16,000.

Of course, it hit peak power well short of either figure.

You are making really good power. You Dyno'ed much higher than me.

Come dyno in Kentucky, I'm sure you'll make more power here.

I really wish I would have documented the conditions now that I think about it. I know it was in the 80s but not sure about humidity or anything like that.

We know some car/engines can dyno higher than the manufacturer official numbers, but that's pretty crazy.

European horses are bigger. EU crank HP roughly translates to US Dynojet wheel HP.

Dynojets typically read high, but what really matters here is the gain from the stock baseline run, which is impressive for just a stg1. Are you still on stage 1, 93oct I assume? Any problems since the flash? I am heavily leaning to going this route...tired of the constant modding and just need a reliable and fun daily.

I moved on to E30 and then eventually a custom full E85 tune. I made an extra +80whp and +60wtq. No issues to report as of yet. I still say Stage 1 93 or Stage 1 E30 are the best bang for buck mods on a daily driver. All you need to do is pump the right fuel and go.

Here are more details on my E85 tuning experience if you're interested.

OEM AFRs taper to around 14 at redline. Very unsafe in my opinion, but I seem to be in the minority on that one.

Regardless, BM3 tune runs lower in the 13s and high 12s at redline. Much safer and protects your components while the increase boost is making more heat. I feel more comfortable beating on the car knowing that.

How are the oil & coolant temps when tracking or running the car hard?

At stage 1 they are perfectly stable. The engine isn't even breaking a sweat.

A question concerning MPPSK: in the advertising, it was state that, unlike for n54 engines, they didn't change the intake part but the exhaust for b58 engines, to make it less restrictive, and therefore they could tune the engine more agressively (or something like that..)

When using a stage 1 93 tune, it there any difference in HP or torque between stock exhaust and MPPSK exhaust ?

I also notes that cars equipped with OPF filter typically produce less hp when tuned. I suppose that the exhaust does affect somehow the power, or is MPPSK just for louder sound ?

There aren't any noticeable hp gains with the MPPSK exhaust because it retains the stock downpipe. The catalytic converter is a big obstruction and robs hp potential. The same goes for the OPF.

Have a 2017 440i w/ MPPSK and 6MT... going in today for BM3 Stage 1 tune to liven her up a bit. Apparently my only real options are choosing octane and burble level. Any thoughts/advice?

I'm usually running 91 Octane, but could easily move that up if it means significantly more power? Tank is currently full of 91. Is that a problem?

Burble level - I don't want to change it at all. It's beautiful as is with MPPSK. Minimal in Comfort Mode, and a perfect amount in Sport Mode. Assuming these can be kept the same?

[BMW in NE]

My 340 xdrive made 298/337 at the wheels stock, and 351/413 on BM3 Stage 1. While the numbers were lower than the OP's the % gain over stock was almost identical.

If you have 91oct, then the BM3 tune isn't really worth it. It will be similar to your MPPSK tune. If you have 93 then that will provide a small bump in power, or if you have E85 available then running E30 will give a more noticeable gain.


You can adjust burbles anywhere from completely disabled to OEM to full aggressive gunshots. Mine are turned off. It just depends on your preference.

You can also disable cold start, adjust boost by gear, enable max cooling modes, and some other options. download the app and you can play with it yourself.

I ended up doing the 93oct tune and what a difference over MPPSK! The way power is delivered at lower RPM's (around 2000-3500) feels a huge boost. Can hear the turbo air whooshing (couldn't before). Feels like a totally different car - I'm in love all over again. It actually pushes you back in the seat which it did not do before. I will mess around with the settings for burble, as it def got louder than the MPPSK (was perfect before - nothing in Comfort, and a bit in Sport)... now it got louder, so I will try to go back to where I was.

Thanks for the info! I will mess around with the settings!

PS - I was following you on Insta for a few months already - nice ride! Was surprised to see a response from you on here haha

[steveindabmer]

I currently have a 440 with MPPSK. Im really considering getting a catted DP and flashing BM3. Probably a stage 2. May even get the HPFP down the line.

Is even a stage 1 really that much better than the MPSSK???

How many horses would a catted, MPPSK exhausted, stage 2 make? Ive been reading about 430hp+?

BTW subbed to your youtube channel kern417. Great stuff, great info.

Yes, Stage 1 93 Oct vs MPPSK is what I did just a few days ago... feels like a totally different car. Massive difference at low RPM's makes it. I was somewhat underwhelmed with the power experienced with MPPSK at low revs... this changed everything - actually pushes you back in your seat and you get hear the whoosh of the turbo. Well worth it. I think Stg 2 only makes sense if you have other components that are not stock (I did not - MPPSK only).

Stage 1 91 octane: up to 18% HP / 26% TQ
Stage 1 93 octane: up to 20% HP / 26% TQ
Stage 1 E30 octane: up to 25% HP / 30% TQ
Stage 2 91 octane: up to 24% HP / 32% TQ
Stage 2 93 octane: up to 26% HP / 32% TQ
Stage 2 E30 octane: up to 30% HP / 35% TQ
