Your 08 will be fine. I was Uprev's guinea pig for the new computers on the 08 models. I think the number is on the ecu, if not I think you can call a parts house with your vin # and they can get it for you. I think. I just went to uprev personally and they hooked their laptop up to my ECU via my obdII port and got my ECU info from that data download they did. If you are going to a local uprev protuner, they should be able to do the same.
