And never trust a salesman, most of them don't know shit about anything. They will said whatever it takes to get it sold.
Tune and pulley will void the engine warranty.

Technically, no, your dealer cannot void your warranty solely based on the fact that you possess a modified vehicle. But depending on your dealer or SA, they most certainly can try. Put it this way. If you have exhaust and your suspension blows, you'll probably be ok. If you have exhaust and your motor goes bad, depending on your dealer, they may or may not try to void your motor warranty, and if they do, the burden of proof comes down to you.

As an practical example, my friend went to a dealership with 335i that was, with the exception of VMR wheels, 100% stock. The dealer tried to void his suspension warranty.

That being said, the most important thing is to have a good relationship with your SA, and constantly give them 5 stars on their evaluation (This is assuming they DID deserve it.). Nothing they like more than getting paid for doing their job right.
