A Mk1 Is For Life, Not Just For Fun

Hi Folks.
The car is lagging terribly on acceleration. 3rd/4th gear seem to lose power on acceleration, then it catches up & begins to increase.
I have changed the fuel & the air filters, replaced with BOSCH & it improved almost immediately. However, 2 weeks on, it has started doing it again & as badly as it was before.
I am wondering if it's the turbo, but confused why it improved after filter changes.
Any help would be gratefully received. Thanks.
