    If it chokes or splutters the instant it boosts, then its more often then not due to an air leak in the cooler piping somewhere. Or a loose hose clamp.
    If its able to boost a little before it splutters/chokes, then your looking at too much boost, or spark issues or fuel delivery issues. From my experiences with the RB20 if you run too much boost you can clearly hear the turbo 'overspooling', but i dont think that applies to all turbo types.
    Hit me up with some reputation points if i've helped you out! (Star in the bottom left!) Cheers!
