How many volts do the fuel pump get with the engine running? Could be running lean...

Judging by the plugs after a few hours use I'd guess it's not running lean:

than you have to start from the beginning, checking the system and control pressure, replace all the vacuum hoses, check if the idle and WOT switches work correctly, if the rotor is the correct one... and so on

This really sounds like an air leak to me, have you pressure tested for this yet?

Have made quite a bit of progress with this, contact cleaner has been an absolute saviour!
The window switch and the dodgy digital dash just needed the contacts cleaning and now are working perfectly. The radio just had to be plugged in at the battery. It is also running much better having cleaned the air temperature sensor on the IM.
A boost leak test is next on the list which might improve it further.
It's great to be able to take it for a drive and actually know the revs and speed I'm doing now!Comment

Has it got the ECU mod and WG spring wound down?Comment

The WG spring has been wound down so I would assume that the ECU mod has been done too, haven't had a look inside yet though.
It does go well, I'm just used to ~380 in the S2 which trounces almost anything.
Had a van come up behind me yesterday which I couldn't shake off...Comment

Yeah, in stock form with the spring and mod they have a nice midrange push but nothing up the top end. Treser big valve head, more fuel and hybrid turbo helps [emoji6]Comment

Have been doing some boost leak testing! The biggest leak found so far seems to be coming from the throttle body shaft, on the cable side...
Can the seals be replaced does anyone know?
