haha thanks for the shout out BLK but it is kind of true... basically you can get away with minor bolt ons that you can switch for stock when something goes wrong. Unless you drive a BMW where most 335 owners including my friend took out his chip because the computer tell the dealer when you go in for an oil change that you put in a chip. Also the 2008 and up beemers have a camera which records your engine when it is being tampered with. pretty bad...basically wait till your warranty is up and mod the hell out of your car!
