The thread posted is going to very helpful, but also check your MAP sensor filter. There are some newer strategies depending on your Firmware Version that allow you to filter the MAP at higher RPM, but not at low RPM where it can cause poor throttle response. look under sensor setup, and MAP sensor.

If you use MAP filter try the new software (1.139)
In 1.131 we improved the MAP sensor readings stability so less (or even no) filtering is required.
