Mk4 Di pump tuning

[BUNGAL]

My pump on my 80ps mk4 Transit packed up,
I bought another engine and swapped the pump over,
It started straight away but it’s a lot slower,
Will still do 60 mph on the motorway but it has half the torque it used to,

Hit a hill and your down to 30 mph

The new pump was off a 70 ps engine,

Is there anything I can do or anyone around bristol who can look st it for me?

You could try turning up the fuelling on the pump, see post here for where the screws are located on the pump and which does what.
