Not true at all... stacking fixes the flatline issue by allowing a lower load setting in the dme since you use the piggyback to control boost. Is it the best way to do things, maybe not. Does it work, yes, you won't get full timing but it will recover.

If your engine was a single cylinder engine I would agree. With that graph I can only be 1/6th in agreement with you.
