Hi all I've been using the Excal II for about 5 months now and it's been great. I had to reinstall the factory setting cause I was taking my 150 for maintenance, and I got a trouble code P0174. I have the airforce one I'm sure this is the problem. Is that code a bad code should I be worried. It doesn't come on when I put Mikes custom tunes on, it just comes on when the factory tune is back on. Would it be all right just to clear it and run it with the factory tune?
