primary injector size . and idle

So im pulling my motor due to a oil line that blew off on highway.
The previous owner told me that he had 850 primarys and 1300cc secondary s. After removing the injectors I found 1200cc primary s w 1300 cc sec. On e85 it would only idle good at 11.8 to 12.4 @1100 rpm. Not horrible but it could be better. Would I be better to run id 1000 pri. Id 2000 sec.
I have a lt10 s.
Anyone run theese injectors w microtech w good luck?
Let me know what you guys think

You should have no problem running those injectors on the Microtech.

Those idle ratios sound about right for E85.

Would there be much difference in idle quality with the id 1000 vs the bosch 1200cc. Or would a smaller id injector be better in primary

It wouldn't matter based on the amount of PW required to supply E85, and the very crude PW control the Microtech gives.
