I am not sure exactly where I should put this, so I figure stock will do fine. I got the scangauge2 and I was messing aroung with it and I had one of the gauges on the IGN setting. At idle in park, it was 8. Idle with it in drive was 14ish. On the highway going home, i noticed that when I was "coasting" it was 30-55 and when i gunned it would go to 8-12. Once time, I dropped it into 2nd and gunned it almost to redline and the IGN was 2. Can someone explain this to me on what happens? I also have the timing mod done.
