light load surge finally nailed

[fasterfaster]

Was on the Gen II this topic, and on the gen I would be a little concerned (read very) that when you pulled the line and fuel pressure rises whilst mapping then drops leavin ya lean after ? Or as RB asks ................. are you leaving it off ? I'd only do it if I could monitor pressure whilst doing so as the map settings are only relative to fuel pressure at the time of setting.
