Hello;

I am the owner of 2016 model M-pack 118i (136HP) 3 cylinder engine. I'd like to make it more custom, i am not experienced on tuning. I have some questions;

- what is the benefit to change Intercooler with better one ?
- exhaust tuning is only for optics or how much effect to the performance ?
- i am thinking ACS for the tuning but i heart that they advice 98 RON petrolium after tuning process, is it same for all chiptuning companies ? do i need to continue with 98 RON to have bigger power, or i can continue with 95 RON.

Do you have any other recommendations for the performance improvement ?

Thank you all
