FWIW I don’t do the BMP that way in my 231 (pulling straight back until deceleration). The reason is turbo lag. So in the 231, if you pull back that fast the turbo is going to follow soon after and you will find yourself in “too lean” territory, then will push the knob back in, whereupon you will be powered up again and who knows where, lean, rich, or at peak. I have the vernier knob. I roll it back steadily until I get the fuel flow I want. Just takes a few seconds, I don’t dawdle. You want to make it smooth and let the turbo follow along as you do it.
