I agree, except for on a stock 17-16 second automatic fwd with a tight converter you will see 200-300 more rpms if you flash the converter, and trust me you need all those rpms you can get on the stock converter.
One a reworked converter like mine from Edge Racing, I'll get 200-300 more rpm on the foot brake about 3700-3800rpm while only getting 3500 flashing it.
My stock converter would foot brake at 2200rpm and flash at 2400-2500rpm.
