IVE been talking to some ppl bout tuning the HR n most of them said that the HR tunes it self wen ever there is a aftermarket part installed. is this tru? or is there more to this story thx for the help.

 

Each time you add a mod, the ecu adjusts itself to get used to it. However, it's not going to all of the sudden result in a big hp change that you can feel. For real tuning, check out the threads on Technosquare and Osiris UpRev. Also, use complete sentences next time (if you want people to respond).
