he needs to at least get an s-afc on it to allow the car to run.
i'm willing to bet that the blow off valve isn't recirculated, and that, combined with the extra fuel, are not letting the car run.
i wouldn't try to diagnose the smoke until you get the car where it should be running properly. get an s-afc on there as a temporary use to diagnose, then get the car a worthy ECU tune (rs enthalpy is in the area, as is martin's tunes at zfever).
technically you should be able to put the stock 270cc injectors back in, and the car should be able to be driven around in cruising mode and idle. (if you do that, DO NOT GET ON IT or else boom) if the car idles and drives down the street and back ok with the stock injectors, then your problem is likely the tune. if the car is still smoking, it could be the turbo or another issue.
