I haven't had a timing light on the car yet. I know at the track I advanced it a little it picked up 2 tenths an 2mph in the 1/8. Then I came back an advanced it a little more and it was hard to start. so I turned it back down a little and it fired right up. But it ran the same. I was shifting at 6500 rpm then I came back after a cool down an turn up the shift light to 7K It ran the same time but it picked up 2mph.
