Rock N' Roll, Mike!!
I'd say you knocked it clear
outa the Park, guy! And this was your first one...(low ominous rumble of kettledrums and low brass ala Wagner...)
I symbolically shake your hand, Sir! Sounds like you really studied beforehand. Those are Awesome results...Does anyone realize how difficult it IS to achieve over forty Percent gains in MPG?? On a car that already did quite well? Without the Groove I say it's about impossible especially in the time spent.
THIS is a true testimonial of what is really possible w/ proper use of what we have with the Groove. Having an Available Technology to obtain results such as yours, Mike, is a Godsend IMHO. Especially being able to get these results so simply. And you haven't even done plug re-gapping, PCV re-routing, geez...!!
I'm unfamiliar with either your Toyota or your Windstar, others likely are. Dig in and look all round the site, and don't forget the service bulletins on Ron's youtube channel. I just watched a few of 'em and re-learned a couple things.
Anyhow, Congrats on great first time results!!
