There are a lot of great converters out there. Vigilante, Yank, Circle D, Pro-Torque, TCI....however there is no such thing as a 3500 stall that drives like a stock converter.
At what boost are you seeing 3500 since you have data? Once you learn what stall speed is on a turbo converter you will understand why they don't have stall speeds.
The Vigilante multi-disc has been faster than any other lock-up.
The more power a car makes, the more a converter slips. A car running 110mph in the traps may have 4% slip, same car and converter at 120 may be 10%. That's just how they work.
