how much rwhp am i losing with the th400. i ran 13.47 with the 4l60e and stock stall with a 2.0 60' and a 13.30 after with a vig.3200 and a 1.92 60'. i was hoping for at least a 13.2-.1 with the different stall, i know the th400 soaks up a little more power but about how much. i havent been dyno'd at all so i have nothing to compare before and after.
