A mate just bought a '90 saff, As far as I can make out its has a stage 1 conversion, It has dark blue(4x4 injectors I think?) and a 4x4 dizzy cap fitted with magnecor leads. Its boosting to 1.1 bar but sometimes will only go to 0.5 bar. When started from cold the idle is all over the place from about 400-1500 untill it starts to warm up and then settles about 1000rpm but when you are driving it keeps stalling at idle. Every now and again it gets the usual cossie misfire too.
