535 tune or chip

new member here and looking for info on a tune or chip for the 2007-2008 535i. is it a flash of the PCM or a inline chip that modifies the boost? with the chip is it faster than a 550? what about a CPO vehicle with a extended warranty from dealer will it void that warranty? can it be removed or backed out without leaving a signiture?
