I'm running the numbers below on my BD box, and the sled is running way lean when coming down after a climb - just breaking on the engine (if you know what I mean). When going below 5000rmps through 3000 rpms, the air fuel goes lean (A/F 15-16) and egt drops down to 4-500 farenheit.
If I add on MD(edit: I see where the problem is, gonna adjust the LO setting...) at 3 and 5000rpms, it gets a little richer at deceleration. But then the acceleration sucks... Tried to leave the numbers as is, and add on negative boost - but same results then also.
Running on avgas, with 4-5 psi boost. The boost kicks in at 4500-5000rpms, and runs great at acceleration.
Really appreciate suggestions on these numbers!

I already know that other fuel boxes are easier to tune, but this is the box I'm using this season.
