I believe the speed to be very accurate based on visual of Tach (tough to see speedo as am sure you know)- was in 5th gear and around 6000 RPM. But agree HLT does occasionally get bogged down on data update. Again for fun track day it is more than adequate and provides good feedback and insight- I don't track enough to drop a $K or more on data aquisition and very pleased with HLT performance albeit not perfect. I've done about a dozen track days at The Glen and have picked up a few MPH different segements over the past 3 years. I love the Esses and the Z really handles well so you can push up the hill thru the curves. In other lap vids I was pretty consistently hitting 126..127..128 and would typically be gaining on other cars in this section of track and staying with the 911's (Traffic vid) so I think the 129 MPH is correct
