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.

BMW e91 325d (automatic) (stage1)

stage 2 is a remap with dpf removed,but you shpould have left it in,only slight marginal gains,and illegal which cancels that out,hope you have had gearbox serviced before any powerr upgrade

So i dont need to upgrade Intercooler, injectors or gearbox to remap to stage 2?
I heard the need to upgrade modifications to the car as it may not withstand the full power of stage 2
