Hi, a year or two ago I read a post here from someone that had their tuner "detune" (for lack of a better word) his M2 so that it would mimic an NA car pulling to 6500RPM instead of going flat from 5500RPM to 6500RPM as they are stock.

I'd really like to read that again and save the dyno chart for future reference. But I can't find it

Does it ring a bell for regulars of the forum, do you recognize the car? Thanks.

Currently bm3 offers a multi map that's 4 in 1. The 4th map is a flat toque map.

[ctt300]

You can make any map a flat torque map by using boost by gear that just really reduces commanded torque request and thus load. Some say 20% torque reduction in all gears works and then you have the same high end power of the map.

Custom tune >>>

[MTWO]

Cheapest thing to try is free and you just use the boost by gear adjustment but really at the end of the day to tailor things exactly how you’d like and if you have the cash for it I’d say grab a custom tune from someone reputable.

I’d like to see something like this too, I’ve fitted a larger intercooler but not chipped yet, I’d like a little more response and pulling harder to the red line

The intercooler did help and felt a bit freer revving after

[PackPride85]

You're not going to get a flat torque curve to 6500 rpm with a stock turbo n55.

[Carrera2RS]

Any tunes that improve 'crispness' and clean revving ?

Edit.

“ Downpipe, intercooler, charge pipes and dyno tune.” - Bob, who owns Stage FP (my tune) did this.

I'm interested as well. Any way to make the car rev more freely like an NA motor and put more of the power and torque as high rpm buildup? Can hardly get anywhere without having to short shift before the car is surging forward like crazy.

Maybe this one?

That’s an upgraded turbo - what I posted was a stock turbo. It made 370whp from 5500-6500rpm, which is great. I don’t think NonM2 N55s can do that.

Jesus, losing 150ft/lbs at 3,000 RPM is one hell of a sacrifice for that curve. Do you think it was worth it?

Why do you need more than 400wtq?

I completely misread that graph on my phone, the torque drop is way less severe than I thought it was.

But to answer your question, why do I need it? Because I think this might be my last (hopefully not, but we will see) ICE car before we swap to electric. So I like it to be a little edgy and overpowered.

Well, we were talking about "linear" powerbands, which make more (or plateau) power towards redline. I mean, I guess I get it what your saying, but I'll be holding off on electric for a while.

You don't "save" the environment by selling new cars that require precious resources.

I don't like the chitzy interiors that are all about "SCREEN SIZE"
I don't want to plan my life around "charging"
They are expensive
They have almost no real resale value once a new model comes out (who wants old deteriorated batteries and old tech?)
Tracking software, including the ability to remotely disable the car by the manufacturer (they can increase and decrease 'battery capacity' over the air) And this isn't even mentioning the camera that will be in every new car in 2026 to monitor drivers.

I say we just stick with what we have and enjoy it for what it is - the 'electric' future is garbage.

I'm thinking downpipes with 200 cell cat and intercooler might be the answer ?

For?
Do what 3t3p did, and grab yourself an MST inlet abd Turbosmart diverter valve in addition to your intercooler. It will improve response and free up additional high rpm power.

For your Downpipe, I would recommend anything other than Wagner.

what I would like to do is improve throttle response and allow it to rev more freely not juts add hp in the midrange and drop off at higher revs moving the peak power lower down the curve

Interested about the diverter and inlet pipe any more insight to what these do ?

Before Milltek 300 cel downpipe.

After as above plus MST turbo inlet V2, DO88 intercooler, forge charge pipe, turbosmart plumback Diverter valve.

Car has BMW major service about six weeks ago.

Bee Pee Also dynoed the inlet at about 10WHP in the upper RPM region. I would also Contact Bob from Stage FP to get a variant of tune I posted prior. You'll notice it hold over 360WHP from 55XXRPM to 6500RPM. Most off the shelf tunes are already losing power after power peak.
