Yes,....have run up to 20 psi. My best result was with the stock cv carb, modified N72V needle and 240 main. The idle circuit was opened up too. I'm running S-2 cams,...mildest available from HD,....I think the exhaust backpressure from the Aerocharger necessitates more fuel from the idle circuit than stock can supply (less signal) Its just in the quest for more power and better midrange,....when i lean it out too much and get a lean backfire the turbo is basically ruined. I can't deal with that. A good old Garrett is almost bulletproof and good enough for aircraft. We''ll see. Your dual plugging is excellent. Jeff Churchill J.C.
