i recently have install a tsi turbo that i purchased from turbokits .com the fuel system that it came with is giving too much fuel running too rich i took off the the external injecters but it is still running to rich and that car still turns off on me if you have any info please contact back
 
Need more info. If it is stalling when you let off the throttle after boosting, then it could be the BOV. If you are venting to the atmosphere, then it is releasing metered air and will cause you to stall. If that's not it, then we need more info on what type of fuel system products and settings you have.
 
sounds to me like it's your bov. Mine does the same thing. Your MAF sensor is reading one thing and with the bov open it is releasing some of the air that you MAF has calculated therefore shutting your engine down or ruff idle depending on how much air is escaping. You can get around this if you run a hose from your bov to your intake BEHIND the MAF sensor to correct this issue. Hope this helps. BTW running rich is a pretty desirable thing to be doing.
