Im a little confused. ...which in reality doesnt take.a lot to do....

car boosted fine on 1st and second turbo.....

had a greddy profec installed and still boosted fine when full BPU

now its like the 2nd turbo just doesnt want to play ball.....the boost controller I have displays a graph which shows the 1st coming on and seems to flatline when 2nd comes on.

no odd noises on or off throttle

any suggestions. ...?
