Well.
Some news:
Was feeling a bit flush so forked out for a wasted spark conversion by msd. After some idiot ( me!!) managed to solder like an ass the car wouldn't start. After discovering the "professional" work it started fine.

Noticed the phase sensor plug was fitted the wrong way around when checking all the damn sensors. Don't blame me it was like that when I got it.

Well.. went out in the car and after letting it get warm full throttle in second gear. Pulled almost to the limiter then a small judder. Tried third. Judders when it hits 5k-6k. So it's out of "limp home mode". But what the hell?

Plugs or what? didn't boost more than 1,3-1,5 bar so shouldn't be boost cut.

Getting a bit tired now..
