Hi all. I'm a newbie to the forum and I'm sure this topic has been discussed at length . However I'm trying to get my head around the tune or don't tune my 2010 N54 335i (still on m/plan) issue.
My initial two items to upgrade would be software and down pipes.
I have people telling me that any tinkering with the software can be detected by BMW even if the map is removed before a service. There is even tuners afraid to get involved with a mplan car.
Also what's better piggyback or ecu mods
I need to make a decision quick as the wife is waiting to use this money![Blah]( "Blah")
Please help
