Hi all,
What are the differences between 110 hp tdi mk4 and 130 or 150 hp tdi mk4?

Engine Management, Injectors, connecting rods, turbo and pistons are the main differences

with a good ecu reprogramming like REVO or a lot of other makes you can make 130-140bhp. But internally the differences between the models is significant. The stronger versions also have a variable turbo.

A *pumpedüse* is a nozzle (injector) and high pressure pump combined in one housing....in dutch: pompverstuiver :biggrin:
