"they should have
reasonable off-idle power with no boost when tuned correctly." I never said they would have full power.
A 300D moves 21.48lb/min at sea level with 12psi boost. At 10k' you would need 22.5psi boost to flow the same amount of air and get the factory 125hp, but that would blow up the turbo from over-speeding. With 12psi you'll get enough air for about 93hp instead.
Thats far better than a non-turbo 300D would fare, it would have just 60hp at 10k',
less than a 240D at sea level!
