None were the exact BR calibration. Even the BR had some tweaks that altered the shift points and kick downs. KZ, CQ, and CR with their corresponding governors arent too far off from a BR but the activity at different throttle angles varies. BR has the latest light throttle 3-4 of all tested. I havent found a true winner yet but the CR8 (its was over the counter vb) is very promising for a 6200+rpm application. It had a 3-1 kickdown at 48mph
. The 1-2 shift was fine up to about 650hp but after that it ran away in 1st and would not up shift. The 2-3 remained around 6200. Im playing with the calibration currently trying to get a 1-2 around 6200. CK sent me some shift valve springs, valves and sleeves. If that doesnt work ill look into the TV limit circuit but its a very sensitive circuit to play with. For 5800-5900@650hp the KC wins hands down. Its very active and predictable when mashing the peddle and gives a nice shift rpm when used with a stock GN governor. This is assuming an effiicient converter too. Loose converter will need a heavier governor or it will not upshift
