I have to agree, I clock about 5 psi at 60 and 9-10 at 70. I have the waste gate set a bit high at 14 and drive it at a max of 12 psi. It will pull 14 psi at half throttle. I need to get an EGT.
By contrast my vw TD gets 2-3 psi at 60.

Diesel engines are nice because the more air you can cram into the cylinders the better the fuel economy and power out put will be.
If you had a boost gauge you may see why there is a fuel economy jump at the higher speeds. At 60 the turbo maybe under such light load it may not be kicking out any boost, at 65 you could be developing 1 or 3 PSI and that small change can make a lot of difference.

Water injection can raise the boost? I thought it was to lower the combustion temp.
