Red dragon 6000 return pipe

Hi

I've tried to figure out which size of pipe would be best to use for a return from a Red Dragon 6000 return pump.

Some info on this pump.
------------------------
Intake pipe: 1.5" (40mm)
Output pipe: 1" (25mm)
Throughput: 1583 GPH (6000 liter)
Max lift: 147" (3.75 meter)
------------------------

My lift hight is about 60" (1.5 meter)

As it says the output from the pump is 1". I've tried using a lot of calculators on the internet to se if it is god idea to use 1.25" or 1.50" pipe instead to increase the GPH. It seems like all the calculator says that the bigger the tube, the more GPH.

But would the flow increase if I use a larger pipe ?

I would use the 1.5" there is a point of no return.
