BMW 3 e91 325d (stage 1 -> stage 2)

foo7steps · 12-03-2021, 02:18 AM

Hello, im new to this forum and kind a new to bmw. Actually had it already for 1.5 years.
So i already removed DPF and upgraded my BMW to stage 1. So my question is what modifications should i do before stage 2 upgrade?
And will my stock gearbox be able to handle the stage 2 or do i need to change it too? And to which one? I prefer the automatic gearbox, so i dont want to change it to mechanic.

what exactly do you mean by stage 1 and 2 in terms of power? how much have you got now?

is this the 3.0 N57 or the 2.5 engine?

Hi, sorry for replying to an old post but just curious as to if you went stage 2 and how it went. Did you notice a big change with the stage 1?
