Yes, all my readings of flow come from the gauge. Would you like me to video tape the gauge operation through a 3rd gear run to redline?

There are instances where the spray curve can be a slight hump, this can be tuned out with restrictors, pump pressure etc. Most of the time this is not necessary. Another cause of this on the DI cars is the DC is skewed, its not entirely like a regular FI slope. Because the DI cars spend the bulk of the IDC range between 45 and 65% in the midrange and power region, there is a small area of resolution.

Anyway, without boring everyone with too much tech stuff, what you can do is turn the gain up until the red light(95%) in the controller just starts to come on at redline. This will spread the Aquamist DC out over the narrow band of the DI fuel injectors. After this you can adjust jetting according to the fluid you will run, and fine tune the gain according to the tuning needs.
