Fuel map below 30kPa should be zeroed. This is engine-braking teritory and there is no need to inject fuel there. It will just pop.

Extra trick:
Advance curve where turbo is supposed to go online can be retarded somewhat to gain response. You can do it later on as you don't know how turbo will react. But say that turbo goes from zero boost (100kPa) to 150kPa between 2400 and 2700 RPM, those cells can be retarded five degrees or so and you'll gain boost responce.
Thanx Goran!

I'm working on it some today, and I'll be adjusting the EFI a little.
