suspected misfire?

[sweet1]

hello people,new member here.i have a leon cupra 180 remapped 7 months ago,everything has been great since having it done,had hyperboost valve fitted,k/n panel filter and irridium tough sparks put in,recently i have noticed what seems like small power losses when accelerating then the power cuts back in again jerking the car,new coil pack fitted a month ago,any ideas on what may be causing this?

when was last time fuel filter changed mate?

could be a boost leak somewhere, have you checked all pipes... is the hyperboost a recirc valve or atmospheric?

check hoses first, especially the ones under the inlet manny, prone to split.
