car falls on its face from a dead stop

i got my car running with my new cam 549/576 lift 230/244 duration still not tuned yet so it runs really rich... and i have an exhaust leak... havent had time to finish everything up getting into busy season at work... but on the way to work today my car would fall on its face from a dead stop and it would shift really hard like i was dumping the clutch but its a automatic... could it be fouled plugs or the converter or the tranny? or something else?

It's probably the tune! You shouldnt be driving a car with that much cam untuned!

MAF sensor? Also, if it ran fine for a day or two then started acting up, could very well be the computer. It will learn slowly, but can only compensate so much, by design.

Exactly. If you're runnin THAT rich, and your exhaust pipes are black, even on the outside, no way in hell it's going to run right. Fix the leak, fix the tune, then we can start diagnosing any other issues you may have.
