Do you have a laptop?
It's best to use a laptop for the tuning where you can go in and get very detailed with transmission parameters.
With a laptop you'll see where you can play with the converter, have it lock in just 3rd, just 4th, or both, or not at all. It has ability to lock and unlock at any rpm and mph you choose. The Quick 4 is a nice piece.
