Boost / air fuel question turboII
hey guys
I have a 88 turboII . Im have a leaning out problem . My basic mods are 2.5" down-pipe back , blow off valve , adjutsable fuel pressure regulator (reading 47psi) and boost/air-fuel gauge . I had a irratic idel proble and solved by fixing a vaccume leak . Now I have noticed that when I roll-into boost , that it kind of stumbles , goes lean on the air-fuel gauge then it picks up , takes off and stays half-way between rich and stoice . Does anybody have an Idea of what this might be . thanks for any and all help .

dont really do that much stuff with fc's but it sounds like you are overboosting and hitting fuel cut for a second, what psi are you at right before it happens and do you have a fcd?
