my guess at the 105s is based on people that have full exhausts run 110-112s, so I'm guessing the reduction in exhaust velocity with the stock pipe is limiting how much air can be processed through the engine.
also, the fact that you have the needles down to the 4-5 clip position and want to go even richer says to me you need to go a bit richer with the mains from where you are.
