Holley Sniper EFI
Changes should be saving, even w/o the dongle. I don't think a dual plane intake is your issue at all. Where is holley at with this? I put you in touch with their tech, and was hoping they could straighten this out. They should have more knowledge than me on the baseline adjustments. The holley rep and I both pointed to timing being the culprit, and i know i responded to some emails of yours with what idle and cruise timing settings to adjust. Did anything come of that?
