Gunter, is your question aimed at me and my car?

I'm tellin ya, my speedo is accurate according to GPS units up to 100/120 and side-of-the-road radar speed signs @ 35/45/50
If so, how about a little background on my car. Let these guys give thier input.
1985. According to John Walker, some of the best compression/leakdown he's ever seen when the car was bought two and a half years ago. Less than 50,000 miles. Regularly dyno's at 202rwhp, and very consistent about it.
Car is STOCK. No chip, no engine mods. 93 octane was used during the run in the pic.
Gunter and I have had some friendly banter about whether or not I reached 140 several weeks ago...Gunter sez no way
Here's a recent pic. Wish the tach had been shown fully. I was still accelerating (although slowly) when I lifted.
