I imagine, however, with the data of the regular b48 with tune getting close to the 300hp range it should be really close.
With the Tune and Downpipe, it breaks traction in 2nd gear when you get on it. There is some TQ steer for sure in 1st, 2nd, and 3rd when you mash the pedal to the floor.

Nop.

Here my F48 2018 25i Xdrive Stage 2.
The haldex works very fine with launch control and the TQ steer is inexistent.



I never see any tire losing traction.

Ps. I use 245/45R19 Dunlop Summer tires in original 19” wheels.

Owo! In Sdrive model, its normal...

But if you really want to do a X1 M you need at least a Xdrive model...
The Haldex work in 50/50 if you use launch control and the gear change is very agressive.

To B48 engine, 300~320hp is OK with stage 2.
With hybrid turbo and WMI (Stage 3) you can add 60~80Hp.

The new 330i with revised B48 do 340hp with Stage 2.
(Have a little bigger turbo, watercooler (not intercooler) and others mods).
