It's like 99% of the women shopping in the Victoria Secrets Catalog and think it will make them look like the models. Put the book down and go back yo your trusty old JC Penny Plus Size book. Whats good for the 6 and 7sec guys doesn't apply to us.
There is a more to locking up a converter then just jumping the A-F terminal and stepping on the gas.
When I did it years ago with a Vigilante converter I found locking it right after the 2-3 shift. Less strain and rpm pull down. If I remember right it netted me a ¼ sec. and 4-5 mph. You also need to keep your rpms in your cams power band. If locking or less/more converter slip knocks you out of it your fighting a losing battle of tuning.
