So the converter won't lock prior to 6,400rpm or 60mph (unlocked) in 2nd gear no matter what. I am pretty sure that is where I lost the mph I did with the converter over the stock converter. The stock converter is basically locked by 3K in first no matter how you try to set it up. The 4C only locks if I have traction from the hit. If I spin, it won't lock till 4th. The problem is that the converter is so loose, to do it's job, that I had to drop 5-7mph out of my 1/2 and my 2/3 shifts as to not hit the limiter which is set 500rpm over the shift points. With the stock ported IM on there it wouldn't lock till after the shift to 3rd. With the MSD, it wants to lock right at the top of second which is very hard to tune for due to the huge mph difference for shifts between locked and unlocked. So now I have to battle with 1mph increments and for the lock up and drop the shift mph by 1 each time so it locks at the very top of 2nd or in the shift. If it hits 3rd not locked up it drags for quite some time before it locks.

I hope all of that made sense.
