So your saying this engine should be able to idle at 900 in gear without it chugging and wanting to die? I've never ran this big of a cam so I really don't know. It just seems to bog down and want to die at that slower idle. I guess I need to get my butt to tuning it... I stay so freaking busy I never have time to mess with it. And I don't have anyone to help me with it... learning as I go. And it's not doing it at cruise speed at 4k rpm. It only does it a few secs after I floor it. Hard acceleration only.
