hey, so i just got the 3.0 v6, im looking to mod the engine with simple bolt on's. just curious what is gonna void my warranty if any of it, and are any of these mod's detrimental to the integrity of the motor? i.e. is it gonna break it down faster. also, i realize i need a tuner to attach to the car, what do those usually run for, and how difficult is it to tune it yourself? otherwise how much does it cost to have someone tune it for you. you sounded knowledgeable, so hopefully you can help. thanks! really just lookin at the cold intake, exhaust and chip combo, with a tune, but afraid its gonna scratch my warranty =/
