So guys, I have a 2015 335 xdrive sports line 300 hp stock because its leased.
I couldn't really wait for the more powerful 2016 bmw 340 xdrive 320 hp or more.
I was wondering. What upgrades I can I do to my car with not breaking lease warranty or spending excessive amounts of money, to be equally fast as a bmw 340 2016 or even a bit quicker. Not sure what bmw has done to make the 340 faster but seems to have the same engine to me.
So I'm looking for advice.
Thanks
