bobad idle

[scherger_16]

got a t28 turbo 550cc injectors z32 maf fmic. when i start the car it wants to die out on me it will rev up and eventually the rpm lower and my vacume lowers also. it idles at 900 and when i slow down to come to a light it stalls out on me i raised my idle up to 1500rpm and it will drop down to 700 when i come to a stop and then will idle back up to 1500. if i let it sit for a min it wants to idle down like it wants to stall out and runs rough and the vacume goes to 15 inches to about 10. car runs really good when its driving.

Do you have any kind of tune at all whatsoever?

ya i sent the stock ecu up for tuning for the maf and injectors and then i drove up to where i got it tuned and they then dyno tuned it for me and they said it had nothing to do with the tune thats causing it to die out like that
