I just put i new pipe on my bike ,and now i need to remap the efi should i take it in to a dealer , or should i buy a fuel programer? which one is better

 

MOST PEOPLE JUST GET THE CONTROLER. I HAVE NEVER HERD OF ANYONE GETTING THERES DONE AT A DEALER. I WOULDNT TRUST MANY DEALERS ANYWAY. I HAVE MINE PRETTY CLOSE BUT STILL MAY TAKE IT TO A DYNO AND HAVE IT SET UP PERFECT.
