I think I know the answer but want some experts to chime in. I have a normally aspirated 3.0 litre 6 cylinder engine running MSII. I have been struggling with tuning and specifically it's running rich no matter what I do. The injectors I was sold are 30 lb. per hour high impedance but it looks like the fuel injector calculator on this forum says I should have 20 lb. I am running TWM ITB's in 46mm size and I'm running 6 injectors one per cylinder. I believe I need smaller injectors what do you guys think?

Jim I'm the guy ( Rick ) in Orlando that you've been helping. In regards to the fuel pressure regulator it is brand new just installed as the one I was running was not a vacumn assisted regulator. I was hoping the injector size was the "smoking gun".

Lance injector open time set at 1.2. Idle pulse width is 1.7 to 1.8. I will have to purchase a hand held vacumn pump to check the fuel regulator. I'll post the results here. Thanks
