Search "boost spike"
That is what you are seeing between gear shifts.
If you are running the new 3.00 map then you would not see this becasue Cobb has calibrated the AP differently to not show this anymore. It is not a real psi number.
With the new map you will now see negative psi at low throttle and idle which is the real value and no boost spikes.
