standard turbo at 21 psi - spinning faster, therefore generating more heat, means higher inlet temp = less dense air.

less dense air means less oxygen.

So this is why Donny's car is 20bhp more than the usual 130 limit for the Rover SDI range and his torque stays high throughout the range, where as mine drops as soon as it peaks?

Quite possibly, as especially with the front mount intercooler, he's getting some nice cool and dense intake temps, enabling him to run more fuel.

Friggerpants drop in torque could be the pump not being adjusted correctly (its a mechanical injection so is hard to set up perfectly).
But there is also the factor that the turbo runs out of puff at high rpm's which adds to the problem.
