If a turbo is not able to fully spool in first (because its a real big one), then second gear would also need to be made slightly shorter to get the turbo spooled, then the preceeding gears should be long to take advantage of a fully spooled turbo.

A fully spooled turbo gives you a wider range of usable power.

the turbo has to respool in EVERY gear, it doesnt stay spooled from the gear before it. you switch gears the BOV bleeds off pressure, the turbo then has to rebuild that pressure when you get back into gear.
