2g shutting off after boost

[bgeclipse]

when i boost and put it back in neutral to prepare to stop the car shuts off,it started happening after i remove the pipe for blow off valve Bdump tube ,and remove the bottom honey comp looking thing on bottom off mass sensor.car boosts fine and idles fine too

Put the hose from the BOV to the intake pipe back on! Unless you have a gm maf setup you need to NOT vent to atmosphere . Doing so without the proper setup will cause you to stall after boosting.

sorry about not explaining well,i didnt remove the bov dump tube completely,i just cut the part thats inside the intake hose,the outer parts is still there.i did it to get more airflow to turbo

Ahh ok sorry, thought you ment you removed the pipe from the bov to the intake. You didnt have a problem with the stalling issue before the mods you did correct? If you didnt have the issue make sure you tightened the clamp for the dump tube back. If its tight I would replace the honeycomb and see if that helps.

Put your MAS back together and do a boost leak test.

I'm having the same exact issue, whenever I come to a stop after boost the rpms go from 7500 to 0 and the car dies...

I just got the turbo and o2housing ported but car was down for about 2years and it was doing it back then too..

Provided your MAS isn't hacked and you have done a boost leak test, I would take a look at the VSS (Vehicle Speed Sensor). That can cause the car to shut off when coming to a stop.

More than likely a boost leak, also make sure the MAF is hooked up correctly, not getting a good signal could be causing it.
