The problem is two-fold.
First off, the injectors are very "small". This means that the actual amount of fuel they can inject during one power stroke is minimal. So your ultimate power potential isn't very high (which is why your EGT stays cool).
Secondly, the compressor on the turbocharger doesn't move very much air (even though it's a later unit).
Thirdly, the high pressure oil pump isn't up to the task of moving very much oil for very long.
The largest gains will be in the shifting....not so much the power although we can eliminate a large amount of smoke.
