Its same as changing the port scalar without changing injectors it just unbalances the port and direct fuel systems.
you better off leaving those alone unless your running E85 and if you do alter them alter both the port scaler and the GDI the same amount percentage wise so they stay balanced.
If your on petrol then don't touch the port scaler or GDI flow tables.
Just adjust the pi/di ratio tables so your using both fuel systems all the time this will increase your overall fueling capacity as you will be splitting your fuel delivery over both systems at all times.
Those error codes indicate you have an actual problem with your DI system. Check your DI computer under bonnet is securely grounded and all mounting bolts care secure, it get its ground via the mount bolts.
