MrM, I got a new battery last June when I got my xfire, and back then I had my alternator tested as well and it was pushing 13.5-14V so I figure the adapter is 1V off in relation to the alternator. I'll have to head to the garage tomorrow and double check it with a multimeter.

I've also done throttle resets and removed the negative battery lead for 30 minutes and it hasn't helped. Torque Pro doesn't show any codes either.

Actually I just thought about it, my negative battery lead looks like crap, I'll shell out the $4 and get a new one and double check the numbers with a multimeter.

Similar issue happened with my friend's Civic, the terminals were so corroded that the car would randomly die and would have no power at all, my xfire isn't that severe but 9/10 with the electrical issues I've had with my underglow and such has been traced back to a bad ground.

I'll keep you all posted.
