RB20 stall after high rev

[Guest Aj-rb20]

Hi when I rev my RB20DET in nuetral and then let go revs dip to 100 or so and sometimes it stalls

Everything is stock except a high flow turbo.

This did not happen as bad before the turbo upgrade. It seems like its choking on boost, do use think i just need a bigger BOV or is ths a sign of engine wear??

Check that the iac valve is not jammed with carbon deposit and also check that it is wound out not all the way in as some are, what is happening is the idle comp valve can't let enough air in to stop the engine revs from dropping right down and stalling
