SCT is still shooting for a November release for SEMA. They are also targeting support through '12 as well.
I don't work with the new engineers like I did back in '05 to '07 which I provided probably half of what's avail for us in the tuning today thats meaningful, but I did highly recommend tire size changing on the x3 revamp. We'll see if they do that or not. I told them you can't charge the price you do for the X3 and not have tire size change like superchips lol.
