I think the AU flash fixed many problems. The negative, as soon as I got it back I felt like they retarded the timing by a bit. Then it was posted on a forum that's exactly what they did. I'm not sure if it's true or not but it feels like it. The truck still hauls azz, but it's just a little bit off-
