It's not only possible, but it is currently being worked on. We have changed the rear ratio but there is just so much going on in the programming that when you change one thing, it changes it elsewhere and messes something else up. It's all about finding the right combination of changes to yield the result we are looking for. It's not far off but I'm limited by what I can do with a car that is 300 miles away from me. We have an E55 trans (which has the same gearing as our SRT6) in a crossfire with a 3.27 rearend so we have a test bed to work on it with. I can't work on it every night after work like I'd like to because of the distance from where I live. We'll get it though and this isn't just to get a N/A in an SRT6 but would also work for any rearend you'd want to fab up to work. To many irons in the fire and not enough hours in the day.
