at idle the car is missing and generally running rough, once i idle it up a bit it smoothes out slightly it isnt too bad when driving untill i boost(8psi) then it starts to spudder and goes nowhere, and i mean nowhere it is faster n/a than it is on boost as is, i am just looking for what this might be.. i am not getting a check engine light, at all.. not even if i un-hook the map sensor wich i kniow would promote a CEL.. let me know if u have any ideas
