163, still have speed limiter, Diablotune partially disabled governor but not all the way. I've hit 163 on approx. 6 different runs, always hits a wall at 163. YouTube - GTO top speed
enjoy.

I brought mine up to about 130 accidentally just after merging onto the highway a week or so after i got it. I figured the overspeed warning would tell me my fun was over, but as it turns out at WOT you can't hear the overspeed chime. Useless!
160+ is just crazy. Not only would 90 OVER the speed limit lose my license, but my wife would sell my car while I was in jail.
I was on a test track and had 3 miles of open road and got to 163 on the digital readout.
I glimpsed at the RPM guage and I was only at 5800 but the speed stayed the same even though my rpm were climing. I had to shut down to be able to safely stop. My rev limiter is set to 7000.
155 when I was at 360 rwhp/360 rwtq. I wonder what I can do now with 516 rwhp/500 rwtq? My speed limiter is set to 200 mph. I think the neighborhood of 175-180 wouldn't be a problem. Since there is no place to do that speed I doubt I'd ever see it.
