Question about cobb, yes i searched

So I just installed stage 1 sport tune for my 335i and see a slight difference but i've heard you feel a bigger difference the day after. I was wondering though, If i wanted to install the stage 1 agressive tune, would i have to uninstall then reinstall the tune to the new agressive one? or can i just plug it in and install new one?

I just installed the stage one sport cobb tune on my 335i. Now, to install the agressive stage one tune, would I have to uninstall the sport tune and then install the agressive or can i just install the agressive with the sport already installed?

I might be wrong here as I'm not running a Cobb but as far as I know it's just a map switch between sport and aggressive. No need to uninstall anything. The actual software got installed when you first installed the Cobb AP. All it's doing now is just changing settings (air/fuel mix, timing, etc.)

Just install the Stage 1 aggressive. It will overwrite the sport tune.

All you do is go to tuning and then change maps.
Aggressive maps are for 93 octane only btw

No need to uninstall and re-install , just switch to the aggressive map.
It takes a few WOTs to get 100% performance after switching maps or re-installing.
