VW GOLF GE TDI PD 150 - 139,000 miles

I have just had the top half of my engine rebuilt as the Cam Shaft had worn. At the same time the garage changed the Head Gasket, Cambelt, and skimmed the head. They found when they test drove the car there was no power till 4,000 revs. All 4 injectors were
then be changed. They then said everything was fine.

When I got the car back I found there was no pull/power till 2,000 rev. The car used to take off like a rocket in low revs as it had been remapped. Also in 6th gear around 70MPH the pull has reduced and so has top end speed.

Is there anything else that could need changing or could be at fault/damaged like delivery of air, fuel, sensors or engine management ect? The car had a remap about 5 years ago so could this be the problem after the rebuild?

The car also need 2 attempts to starts at the moment.
