I'm guessing because they launch so good. Mat Watson car wow video shows this very well .and once the jb4 is turned on it leaves the stock m2 from a launch takes it down to 11.7 your car just seemed slow for some reason. (just for info really my last 2018 F22 I got a 3.89 with a blue spark box fitted using dragy and its a valid run ,that car made 426bhp and 601 nm stock otherwise. this was brake boost launch with lots of wheelspin)

3000 DA will do that every 1000 DA you lose 5% of performance

It will indeed,im at sea level where i am in the uk well 8 metres to be exact .... but the difference between the M2 and the 240i seemed very wrong compared to to the car wow videos and others ive seen. what does your car launch like ? do you get much wheelspin,

I can recall from a couple of his videos , he struggled to get perfect traction and launches.

Even if you only spin wheels for a second , that gives all the advantage to the other car.

And as far as getting a higher octane - you do what - add a few 100 octane race gas gallons , then add a few 91 gallons ?

As others have pointed out, is there indeed a race map specifically for 91?

map 6 or 7 for 93 or if you mix a few gallons of E85

I mentioned the 100 octane race gas because a handful of places in Vegas sell it

According the stats the M240i rear wheel drive variant weighs in at .
1,635 kg (3,604 lbs)

The g87 M2 weighs in heavier at 3968 lbs / 1800 kg.

The xdrive g42 weighs in at
3911 lbs / 1774 kg

this shows that the M2 is the heaviest out of the 3 .

E30 is safe to run without a tune
I mixed 100octane with 91 and calculated mixture to be at 93
But when it ran out i just filled up 10 gallons of 91 and filled 3.4 gallons of E85

You can run up to E35 without a tune, you can also run 100 octane gas, but without a specific map for these fuels, you are not gaining much
