Loss of power! :(

e60 M5
After a clutch and flywheel change my car feels like 250 hp . Im not getting any engine codes.
Anybody any ideas???
when accelerating it feels like the vanos isnt kicking in.It is so slow but it goes up in rpm.
I gutted my cats both and have a tune for that too.
So what could reduce my power and not give any codes?
Vanos? I would guess it would give a code
Fuel pump?
ionic modules?
Please any ideas?
