Hey Terry,

I had a stage 1 that i tried to update the firmware from this thread and I guess its bricked now. Anyway to send it in to get repaired?

I also already bought the upgrade board with obd2 cable and its all hooked up and working. The only thing is on map 1 and 2 when Im on the gas the car bogs down and i have to put it on map4 (stock) which runs fine. I will get a log and post it up.
