after i instal them do you think i will need a retune??? i dont have any chips or an upgraded ecu. all i have is an intake and an exhaust.

You can generally benefit from tuning your car without any modifications.
Then when you start adding parts that allow the engine to breath you can generally see more improvements.

Although depending on what engine you have and how they respond to specific bolt ons some don't do what they claim... "most" stay away from Safc's and ebay chips do some reading, get some books and go from there.

 

To reap the full benefits yes, to get instant improvement no.
