We've had quite a few people do it with transmissions out, not sure if anyone has done it with transmission in as it is possible based on our trials, but I've never heard a forum member do it that way yet, but it's doable.
You'll see about a 1-2 mpg savings on the highway with it. If we get a group of people that want to buy them at the same time I can discount it a bit for all of you. We can keep it in this thread. I'd really only need about 3 or more people to knock the price down a good bit.
later!
