The AFR log looks perfectly fine and you want to lean mixtures during spool.
Im surprised all of the "experts" in here arent asking about cam phasing. Adjusting fuel mixture and timing would not cause that much of a shift in powerband like this. You'd have to physically alter the amount of airflow coming in/out of the head. Knowing that BC cams usually are made off centerline... Im guessing there is a unique cam phase setting on this car (if they were adjusted).

you think huh? give me this guys rom and ill make his spool normal. I do agree certain cams have ****ty grinds though and will alter your TDC so much it throws things off.. this is why they invented adjustable cam gears, so you can degree your cams properly. this guy prob asked for what he got, Mellon isn't stupid.
