Also Matt, back to your original question:

When I first took the truck down the track(Granted with probably 100 less hp), I learned this:
Flashing the converter= higher trap speed
Launching on converter= lower trap speed
But all night, my et's and 60's were all withing a few hundreds. It may be more noticeable with you since your making more power, but flashing the converter seemed to work best for me. I was flashing it from just off idle.(~1300rpm)
