Struggling to accelerate v50t5

Hi all, new here
So here's my problem, I have a v50 t5 04, just recently had it mapped, and somethings not right, the map was reputable and pretty decent, so I don't think it's that, i feel something can't handle it
, from revs 1k to 3k when accelerating, it's like my car is loading, holding boost then releasing it all around the turbo at 3.5k, it stutters and struggles to accelerate, at lower speeds, I'll put my foot down, revs barely go up nor does speed, I get some judderes then boom I'm going 60 in a 30 and my wheels are spinning, it sounds like it's struggling to suck air, or somthing, checked the sparks, they seem fine, checked codes all good their, sorry for the poor description, it's the best I can do as it's blagged my head so much lately, if it helps I get a bit off a whirl when I'm accelerating high revs , not sure if that's the normal turbo

Good suggestions. I changed plugs and coils after a remap. Acceleration is smooth. I picked up a Porsche TCV to replace the stock unit soon.
