Ok first off if this is the wrong place to ask this I do apologize I'm new to this. I have a 97 f150 super cab 4.6 vin.6 with an automatic transmission u code stock truck. Ok here is my story I bought an act x4 tuner. I updated it, hooked it up to my truck, went to the preloaded tunes, chose the 93 octane tune. I installed it per the instructions. Now my truck wont do anything but turn over will not fire up. So I tried to go back to the stock tune and all I get is an error code 21301. Now I'm stuck my truck doesnt run I cant use the tuner and I'm really at a loss and dont know what to do. Any help would be appreciated. Thanks in advance...

 

If it were mine, I would unhook the truck battery and let it sit a few minutes. Hook the battery back up and put a trickle charger on it. Try flashing back to stock and try again.
