OK,

Car is back running again (have been re running battery cables) Seems to start a lot better than it did.

Vacuum leak seems to be sorted (as far as i can tell), as pumping the brakes doesnt affect idling anymore. I have the gotech MAP pipe on its own inlet takeoff, and then the guage and fuel pressure split on the other takeoff.

From looking at the cam (piper) it is currently set up 10 degrees retarded.

the 'AIR TEMP' sensor - it doesnt look to me like it goes anywhere, was casually cable tied to the injector wiring and doesnt have a proper connector or fitting, its a thermistor on some wire. I did try starting and running it with this sensor tucked into the intake hose on the top of the engine but it made no difference and you could hear the air leaking so i took it back out. The gotech manual clearly states this is outside air temp though i checked (straight off of the manual on their website)

Also it seems to be REALLY smokey now, maybe the turbo oil seal or valve stem seals? It wasnt nearly as bad on the journey back from buying it.

Im going to try and get a laptop hooked up to it and maybe go from there? unless there are any obvious checks i can do?
