Yes, not too much eagerness when the engine is only at 2,600RPM.

I’m still in break in, so I have to be careful top end,and keeping it in full DSC for now, but the shift from 40 in 2 into 3 is where I want power the most. Maybe switching to MDM gives a bit more drama in the 2->3 shift?

Hard to explain if you are not past break in and not hammering in sport + mode. MDM won’t do anything for shifting or engine/throttle response, it’s a traction setting that will allow you to have more fun without having TC completely off.

You can hit up to 72mph in 2nd in a 6 speed manual. 40mph in 3rd will put you at about 3.5k-ish rpm range give or take which is certainly out of your power band and boost, that’s why you’re feeling a bit luggish. You can’t expect to slam on the gas and fling forward without some hesitation as your turbos need spool which is what you garner from higher RPM, hence why we down shift to drop a gear in order to build boost.

These are the pros and cons of turbo cars compared to NA or supercharged. Turbo is and always has been punchy as all hell ONCE you’re in the powerband. The more you work with your car, you’ll find out how to build boost quickly by which gears you need to be in in accordance to which speed and RPM.

As for timing issues, it’s very rare there’s something wrong with the car, and more on the user error (not trying to hurt egos here just being honest). This is a 6 speed manual twin turbo inline 6, we can’t expect it to be a supercharged automatic vette and just take off on any given moment. Given everything put into driving this manual, you’ll need really good if not perfect clutch releases, knowledge as ot where your turbo spools out in and where the power is in your gear.

3rd gear is longer than 2nd and 1st (1st is super short), but I promise you it’s rowdy AF IF you know how to use it. Coming from plenty of race cars myself including spending a ton of time in a 458- I can promise you if done correctly, this 6 speed is rowdy, fast, and plenty of fun.

3rd to 4th on the complete limit is where you’ll get pulled over and likely impounded if you’ve built enough turbo- I can promise you this

Of course an auto will be quicker in every way possible as it mitigates user error and timing, automating the process for you without having to think as much as a manual. That’s mainly the reason these tend to do better on the track.

I’ve gapped more cars than I can count in my manual G87- even dropping from 6th to 3rd rolling 65mph on the freeway (don’t do that unless you know what you’re doing). She’s plenty of fast

I did mention the feeling (when flooring at a lower RPM in 3rd) is more reminiscent of timing corrections than turbo lag based on my driving experience. I experienced timing corrections in my previous M240i when trying to push a stage 2 tune with inadequate gas.

My M2 feels like it is going to go, then it stumbles, almost like it is trying to figure out what to do, and then it makes up its mind and screams to redline.

For me, I have this bias that the pump gas available to me is crap and not sufficient at properly feeding my S58. I do have a lot of curiosity to see what data logs look like so I will most likely get a piggyback tune mainly for data logging purposes and giving the car a little more power once I am used to/comfortable with stock power. I still do believe the car could have timing corrections (or less timing advances) in stock format because of poor gas quality.

Overall, I 98% agree with you; that 2% is my biased paranoia about poor fuel quality and my desire to see the data logs to verify. This is just how my brain works.

Hmm that’s an interesting point you do bring up. What has brand and octane are you putting in? You shouldn’t get stumbling unless you’re experiencing the slight turbo lag- but with turbo lag (as you know since you had an M240i) is more of a slow build and then she pops.

I still don’t think there’s anything necessarily wrong unless you could have had a bad break in, in which case mechanical issues could arrive. But even in this case, it’s soooo unlikely that even a poor break in would cause harm, unless you’re redlining it off the lot which I’m sure you did not.

Another few things I can think of off the top of my head is a possible transmission issue or fuel delivery issues (once again, I doubt it’s this).

ECU might need to be checked at BMW. For your paranoia (I get it too trust me) maybe drop it off to BMW before a piggyback tune to make sure all is well?

I finally went over 1200 miles and am here at the dealership waiting for the break-in service to be finished.

Anyone know why it takes 3+ hours?

Lots of cars. The actual service takes all but 30-45 mins if done by a tech that knows what they are doing. Pretty much just oil and diff fluid change with new filter plug and ring.

Dealership is backlogged I assume.

Speaking on my previous car I tried all types of gas around me, Shell 93 octane V power even, and when pushing stage 2 tune I would see timing corrections unless I topped off the tank with a couple gallons of E85. This might have just been how that B58 motor worked and the MHD tuning settings being demanding. But I also wonder if a little ethanol in the S58 could provide a little more oomph and smoothness.

I need to go out and drive some more with the M2. At this point I have only floored the car maybe 7 times so definitely need more experience behind the wheel. If things still feel wonky (and does not feel like the traditional turbo lag feeling) then I will pursue having BMW take a look. The weather looks great the next few days so will be on the road getting the feel down.

I’m thinking about 15 all around with MP HAS once my car arrives. But also not sure if I got the Pirellis then I might need to change the front to 12 due to potential rub. Fingers crossed.

I did see many cars getting serviced later on.

I'm a little bummed that one of my tires had to be replaced as it had an obvious leak, but not going to dwell on it as now I don't need to be so gentle with car any more.

Let her rip!

Finished the job ceramic coating of the wheels and spacer install. Have to say these two pins are very helpful when lining up a wheel and spacer at the same time. 👍

Next up, window tint and a small CF rear spoiler.

[thinking]

It's been a while since I have had this car and I have been working on it slowly. I didn't post before but had a chance today to wash it and take some pictures.

So far this is what I have done:

- Lowered on H&R HAS (~35mm drop)
- Mishimoto skid plate
- Edelweiss (19/20)
- Maxton diffuser
- dahler ATTC
- Black OEM M2 logo
- DIY black wrap to blackout rear reflectors and front air ducts

Still searching for a front splitter but it's really hard to find anything that is good and TÜV compliant

my m2 got delivered and i washed it and waxed it!

now waiting for PPF to be scheduled!

Not harping on you because you didn't know this. But PPF needs to be applied to bare / virgin paint. When you apply a wax and or sealant of any kind on the surface of the paint the people that apply the PPF will have to remove that & strip it off before the film lays down properly. If not, it will will get trapped & the placing of the PPF will be much more difficult for them.

thinking I wish we had this option here in the US. Do you have a body colored roof with no sunroof up there... ?

Shouldn't have waxed it if ppf is being done. Paint correction would have been the better thing to have done.

Wheels and car look perfect! What widths and offset?

Yes, I don’t have carbon or sunroof. This is body colored. I think you have suntoof as stock option? 🤔

I was cruising along at about 35 mph yesterday when I heard and felt a huge clunk sound. I couldn't pull over where I was so I kept driving and there wasn't any additional sounds or clunking. I turned right around a corner and started hearing and feeling a scraping sound. Finally saw a place to pull over. I get out of the car look down and see this. I believe its a sheet of copper that I ran over with my front left wheel spitting it up under the car. The piece went through the car's underbody guard and stopped when it hit the bottom metal of the car.

I don't think this caused any issue but would like to get it up on a lift to take a closer look. Might not be a bad idea either to close up the gash in the underbody guard. Quite the scary moment on the road but could have been worse.

Thank you! I’m glad you like the setup. These are LT3 19x10.5 ET14 and 20x11 ET12. I’m using stock tires with these.
