Dusty was the one that introduced the concept of using 0 on the boost gauge as a stall comparison point rather than the stall rpm against the foot brake before the car tried to overcome the brakes. Before, that was the common way to compare stall (boost against the brakes).
Converter technology in the affordable range has certainly advanced and the behavior of the converter under load has changed as a consequence.
My 9/11 which was supposedly a 3400 stall would go to 4000 without a struggle and it never seemed to catch up at high rpm as it had a very high slippage rate at 6000 rpm. The car felt "slushy" in normal driving with slow response to the gas pedal.
My first vigilante was too tight with the 66 turbo and would only build maybe 6 lbs or so against the brakes and did not want to do much better against the tranny brake. As a result it was not very good off the line but was great from a roll. It was also tight and contrary when the engine was cold.
Last summer I installed another vigilante and it's great when cold, hardly feel it load the engine and the vacuum shows it. It easily goes to about 3200 against the brake and hesitates for the boost to come up and when it does, it then flashes on up to around 3900 or so. Best of all, it drives like a stock converter which helps the gas mileage. It changed the character of the car completely.
Bought another mopar converter from Dusty the other day.
