Got my car remapped and fixed as it wasnt boosting correctly.
Turbo to manifold gasket was knackered and n75.
It is now chugging on idle sounds like its trying to stall.
Also on constant steady acceleration it is learching forward and holding back constantly.
Injector issue?
Doubt its the pump as these either work or dont generally.
Fuel filter was changed including oil which the engine was flushed before the change.
Spark plugs have also been replaced with the best possible.
Any help as i think it is fueling but not too sure

Have you been able to read any codes, if you haven't got VCDS then a cheap code reader will point you in the right direction.

Also worth checking the coil packs as one could be on it's way out.

You won't often get a code if a coilpack is faulty. Pull them out and have a look. Failing ones are often caked up with crap

Ill replace all four as they look old anyway and if ones gone the others probably wont be far behind.
