LT10C boost is not linear
 

Hi my car currently is boosting 10psi but when i see the logs the map sensor is not steady, it goes from 10 to 8 then to 9 and stays oscillating ... is this normal ? i saw a youtube video from fullboost where the guy changes the MAPLAG factor and for him it works... can i do that too? has anyone played with the microtech maplag factor? or is this behavior normal?? thanks
