Thanks for providing examples.
FYI for anyone who doesn't want to google here's what I found:
[ame="http://en.wikipedia.org/wiki/Mazdaspeed3"]Mazdaspeed3 - Wikipedia, the free encyclopedia[/ame] (no citation though)
https://www.accessecu.com/support/do...scriptions.pdf (p. 48, references a table that limits the amount of torque the crankshaft puts out)
(couldn't find anything solid on the Volvo)
It seems like both those vehicles limit the boost available depending on the gear being used for various reasons, be it torque steer, fuel economy or to "protect the transmission".
Thanks, :happy0180:
