What type of ebc is it?
I have a Greddy Profec B II i'm going to be installing soon, and I found the manual really handy in explaining all the settings (obviously not in what they should be) but in relation to each other.
For example mine says if you're getting boost spikes is commonly due to the START BOOST setting being to close to the SET setting. (i.e. if you set the solenoid not to open until there's 1.2 bar behind it, then there will be a spike, however if you set it start opening at say 0.8 bar the controller has a much better chance of controlling the boost) and finding the right settings takes time and very incremental adjustments.
also the settings are a percentage of solenoid duty not the turbo.
