As an aside, the Denso logic makes this quite effective since engine load isn't just a raw MAF value but rather an engine speed (/rev) corrected load variable. So adding a breakpoint just above the desired engine load and then another one just above that and mapping in substantial ignition retard does the job very well. Arguably better than a rather simple MAP induced cut which is oblivious to any thing that would change engine VE and result in a condition where the ECU sees same nominal MAP value with vastly different engine load.

Gotcha.
