The problem lately is towards top of track the wideband leans out and will hit upper 13s and lose power/ break up. Ive jetted up and down and changed bleeds to no prevail. I have a 16x4 KN filter w the element lid but switched to the chrome lid and still no change. Running out of ideas

Drag only car? Why would you not square up the jets? why 90/100? Try 95 square.
