i was told that i was running rich at idle but why...the setup that im using is drag manifold, t3/t4 turbo, fmu, stock injectors, aem fuel rail, fuel regulator. at idle the car sounds like its about to die and flooding noises are noticable. the car stumbles at low rpms but when the turbo spools it rides fine or when the throttle is open half way around 35k. when i barley put the turbo in(2 weeks ago) i installed 440cc injectors but the car just flooded. My question is people that go turbo with simular setups dont have this sort of problem and they r using 550 or so and idles fine.(a friend of a friend that is using 550 in his zc/single cam vtech turbo)...whats going on?

 

Are you using anything besides a fmu to control fuel?
