Self explanatory really!

Full throttle the car feels quite laggy and holds back

- feels reluctant to rev to the red line, but if boosting at more like 3/4 throttle it seems to be ok and sails along quite happily.

Boost looks to be holding at 1.15 bar regardless

- does that rule boost leak out? I recently had the clutch changed and it's felt a bit slouchy ever since so perhaps a vac line has been nicked or come off.

Doesn't feel like clutch slip and it shouldn't be slipping on a CT20 anyway

(Exedy Stage 1).

I've done a few hundred miles since the clutch swap so that should rule out oil/grime on the faces and breaking the clutch in.

I changed the spark plugs earlier this year to NGK Iridium 7, will check the dizzy cap and rotor arm tomorrow if I get time.

The leads look ok but I've got a spare set I can swap in to try.

Would a bunged up fuel filter or dying fuel pump cause these symptoms? AFAIK they're both original.
