i think my stall is to hi for my car when im crusing and i let off the gas my rpms go to zero and when i stomp on the gas my tach will flash to about 3200 rpms so i assume i have a 3200 stall

with 373s and 3200 stall i think all my power is being lost in the converter

 

last setup flashed to 5100 when i go wot in 3rd gear... Had the same feeling as you that the converter was "eating" up hp, but 10,98 on 1/4 whit a 2-3 1/10 of letting of the pedal to let the tranny shift says that it worked OK.
