whats the diff between flash and stall?
years ago I bought a vig 2600rpm converter,but during the dynotune session they told me it flashed at about 3500,perfect for the hotcam at the time but now w/cc306 it may do what?

Fresh from Yanks homepage:
Basically flash is what you see when you peg the pedal, and the inertia the engine creates as it revs up pushes the converter slightly past its stall speed. I've heard anywhere from 100 rpms, to 3-400 rpms is common, depending on what level of torque your car makes.
Flash stall is the maximum your engine's torque can stall a torque converter. In essence flash stall and full stall are nearly identical. If you had a transbrake, you could find full stall by putting your foot to the floor and reading your tach. For argument sake, let's say we're testing a 3500 stall Yank ST 3500. If you had a transbrake, you would see around 3500 rpms. If your motor was at idle and then you suddenly floored the throttle, you might see slightly more (maybe 100 rpm more) stall for a half second as the momentum of the motor's internals "flashed" the converter a small bit above its true stall rating.
