low rpm miss

[first turbo]

I,ve had this problem since i've had the car starts good but as soon as it starts to take fuel has a flat spot seems to run fine at wot but i might not be noticing it. some times when slowing down for a stop it will stall.Just installed new injectors chip plugs,no help.A friend with more experience then myself on these cars said my scanmaster reading are in line. 36lb blue tops fuel pressure 42 with line off.

Thanks
