So got the car going. p59 3bar sd. Fic1200 ngk tr7ef plugs at .018 base fuel pressure is 38 in effort to lean out idle. Car ran great! At 10psi 13⁰ timing pump 91. Drove it back and forth to work for a week or so logging doing ve corrections the whole time. Then kind of with out warning it started popping/fluttering at the transition from vac to boost. If you floor it it kind of pulls thru but runs poorly. Still makes 10psi but has no power at all. Timing is stable .83-.85 on fuel in power .95 cruise. Plug wires look fine. Just put another set of plugs in gapped at .018. No affect on the issue. Thought maybe couls could be heating up. Possibly plugged injectors? When it starts popping it goes from commanded fuel of .83 real lean the real rich and the boost gauge just bounces all over the place.
