Welp. Customer walked in the shop today hanging his head, and said "You were right on two counts, Chris." I asked "How so?". He said, the Check Engine Light came on, and the kit didn't work on his vehicle. He actually reported a loss of fuel economy by over 9%. Whoops!

If the check engine light came on, wouldn't that put the engine into a limp home mode and be running rich as a default? That would account for the loss in fuel economy. I've had the check engine light come on a few times in my 2005 Grand Caravan and the loss in fuel mileage was terrible.
