In threary, if you upgrade the exhauste to 90mm on a 125i you will be able to use the M chip (mapped) for the 328i when released and punch it out to 255kw
Any suggestion where to do that in Aus? I am very into mod like 10 years ago. Need to keep up with who do some good mod in the country now
I have installed a sports muffler on mine to give at least a bit of noise to the car and also a drop in k&n air filter. Not a massive change in performance, but I am awaiting the BMS tune designed for the 328 this week so that should definitely increase performance
