How much boost you use at cruise depends on engine load, my vehicle runs 9psi boost when cruising at 100km/h, the EGT's run around 430 deg C upstream of the turbo in this situation. But planting my right foot delivers 20psi at that rpm.
Unlike a petrol engine, boost at cruise doesn't hurt fuel economy on a diesel, it actually helps a little.

How many different exhaust housing sizes is there? I can find t3/t4 with A/R 50.. really cheap on e-bay
