01 yzf 426 jetting

I just put a procircuit 496 ( the 96 db quiet model) and it now falls on its face in the mid range, runs like poop. Im at sea level. Any help would be great!

what are your present settings. I am at sea level in Seattle and ended up with a 168 main, clip 3 on the needle, 45 pilot, and fuel screw at 1.75 out with an FMF Power core IV slip on with stock header
