If you are using two injectors, there is often no need to use a restrictor. Alternatively you can reduce the flow via the H3's gain trimmer.

Until you have ironed out the strange IDC reading from the HFS-3, it is best to leave the above for the time being.

I suggest linking the FDC jumper and watecg the gauge displying the F-IDC. Only after we have established the system is reading the iDC correctly, we should not go any further. One thing at a time.

There are many 997/6 installs over the years, this one is not normal. Please tell me the result of the FDC link. I assume the system is set to IDC% triggered rather MPS.
