i want to know if i need to get a custom tune for my car. here is a list of my mods, pacsetter long tube headers, pacsetter O/R X-Pipe, K&N fipk 2, SLP loudmouth ones. and i will be getting a 75mm throttle body soon. i am just worried about my air/fuel ratio. my other problem is i am stationed in germany right now and wont be back to the states in about three more years at least not with my car anyways.
