The amount of boost isn't really relevant, the torque is. Mine is around 300lb/ft and is actually quite flat. It couldn't be a more gearbox friendly torque curve really.
Power is power at the end of the day. The BC 'box is rated to around 150lb/ft AFAIK and whether you have the power by way of high comp/low boost or low comp/high boost, if it has the power, it will break the gearbox.
I upgraded to IB5's several years ago and have spanked alot of those too.
