Back to a BMW...

07-24-2012, 10:05 PM
So I left to the Benz world for 3 months.. I am back now, got a 2010 535i CPO, sport package, premium package, comfort access, m tech, Nav, iPod, XM etc...

I want to do some mods... Any ideas?

I def want to do the chip, but I have heard numerous stories about cars overheating, needing new plugs etc...

I figured you guys would know..

Any performance upgrades for more horsepower such as increased boost will require more components to be perfect operating condition - any weakness will be shown. So yes, one might need new plugs, injectors, coils, etc as needed when problems such as misfires are experienced.

Oil and water temps must always be managed properly when tuning above stock performance but that is more of an issue if you plan to do long track sessions.
