Step 3 was to adjust the firing curve and remove the revlimit. But they did not have dyno figures from that yet but says that it removes the well known mid range dip




Is this true, that there's a "well known" mid-range dip? I think that's what I'm detecting at hwy speeds. Someone here suggested changing the jetting/needles, but it doesn't feel like a mixture problem to me. I've suspected it might be the advance curve, but the only way to know would be to examine the data, which I don't have. How is the curve changed? Can dealers do this?
