If it's a MAF car it probably doesn't just stop adding fuel at a magical airflow number. If it's a MAP sensor car you can tell whether it can measure boost by turning the key on and seeing whether the signal line is close to 5v. If it's in the 2-3v range it will measure boost. If they didnt add ANY fuel they would have blown up before they made it back from Vitesse to the dealerships.
Even if the MAF was reading the correct airflow, the ECU would have been aiming for stoich. That's a bit lean for boosties although it would survive for a while.
I wouldn't use an FMU, though, even with an uprated fuel pump. Use electronics such as the Voodoo Box from FM to increase the injector duty cycle under positive pressure, it's a much cleaner way to do things. Make sure you spoof the O2 signal as well so the stock ECU doesn't see the rich condition and try to compensate.
Excuse my lack of tech savy, the engine is being refreshed completely and the builder is sorting the fuel requirements to suit the engine with boost. I will endeavour to find out more details on how.
This is awesome glad see it being saved.
