Call back or email back whome ever you spoke to and tell them to try a proper dyno ... you know, the one that is too far of a drive ...
So, since we don't know what you make at the flywheel, I think 900+ is a bit of an exageration.
Do you have test data on the drive train loss for an AOD with an open converter and 8.8 IRS from a "proper dyno" to support your statement ?
Unless you do, the 20% estimate for AOD and another 5% for open converter sounds like a reasonable number to me.
