jets for 3sgte with 650 cc injectors

If the IDC is artificially low, as in the case of 60%IDC being max then two things can be done. 1) is two take IDC into the calculation and run an artificially large jet to get the CC's you want, or 2) use the gain function of the controller to set the Aquamist to hit just about 95%DC at your rev-limiter/redline with the jetting to get the job done.

The restrictor is used to match the inlet orifice of the valve to the jetting. So regardless of any IDC, match the total jet size CC to the restrictor size CC.

Low IDC jetting can be accurate depending on how you setup the system. Many folks can make a mess of a perfectly good system, with proper installation, and looking at the setup, as you are, they can be made to function very well.

The .8 jet and .7mm restrictor are about right for the injectors. If you want to use a smaller jet and restrictor and use the gain to get 100% from the jet you can do that as well.
You are using the dynamic range of the system a bit better in the latter scenario.
