    I always scale mine to what ever boost im seeing. you lose some resolution down low when doing this but its the only way to get better control in the higher boost spots. Without doing this the PCM just interpolates the data and you could end up running more timing/fuel than you want without being able to have control of it. In my opinion its the right way to go about it.
