Does anyone know what I should be shooting for timing-wise while dialing in my AM HFS system? I think it's 10 degrees, after it recovers post-shift. I've also noticed that is dives to 5-8 in higher gears when you give it some shoe. If I roll into the throttle more gently it will stay between 10 and 14. Do I need to adjust for more methanol sooner, or change to an IDC-trigger and set the threshold lower? Thanks very much for any assistance.
