May need a different cable.

Since you are using an air flow correction you want the closest injectors to factory as possible, aka the smallest ones you can get away with. 80% IDC's is fine for most injectors, when you are constantly running them around 90+ is when you can see failures over time.
The 450's will allow for more degree of control over the 550's. Most of this has been covered on 3si.org, very specific information to the 3s.
