It is chattering slightly when letting off throttle (like original plastic bosch ones do when there starting to go tits up), which it didn't do when i bought the car, also wanting a remap in the future so it would be a weak point. May also be losing boost although no fault codes too suggest it is.
Just with not knowing what make it is i don't know how good it is quality wise and whether it will take an increase in boost pressure or whether i can get a service kit for it. Hence a change to a forge item is gonna be done soon.
