The P30ff Code will show as soon as the targeted boost pressure isn't met.
So if you took it into a shop and they just replaced plugs/coil packs and didn't mess with anything. I wouldn't think that was the cause.
You're misfiring (bad plug or coil pack) even tho they are new. And its throwing the code, I have had the P30ff light come on when I was having bad misfires. Is the car "surging" after 4k rpm?
