Bright red is a .7mm and dark red is a .8mm. Assuming this combo you are spraying about 670cc. I'm not sure at what RPM this comes on at at WOT, and does it come on at close to WOT or partial throttle settings as well? Anyway, with 780cc injectors and 100% meth, using the same jet with the higher psi pump, you will have 790cc of jetting. Now, at the cut in point, which maybe sooner or at less load than the HFS-1 depending upon how you set it, it will track IDC 1:1 at the cut in point. After that, you can adjust the gain function to add or subtract duty cycle with the slpoe of the line pinned at the cut-in point and hinging from there. You can add or subtract up to 20% plus or minus. I suspect you will have a little less in the midrange than you are used to but more as the revs climb if the trimmers are left in the factory settings. You could go with bigger jets, and trim the gain way down to flatten out the curve to make the unit similar to what you are used to if you like.

One thing to try, is to download the HFS-6 trimmer excel worksheet, and leave the MAP compensation(set to 5v) and IDC trim(12 o'clock position) untouched then you can play with the curves to see what you have now and what different configurations the 3 will give you.
