I bought one of those gtech meters, it was a waste of money. The 1/4 mile is somewhat accurate in the elapsed time but way off for the trap speed. At the strip I have ran a
[email protected] MPH without launching. I figured I could run a little lower with a good launch maybe a 15.3 or 15.4. I got the meter and a botched run was 15.7 and a good/perfect run was 15.2. The traps were at like 98 mph though. So the times for me weren't too far off but the traps were.
The one that said the Lancer ran a 14.X was def. off though. I would recommend nobody buy them because they are not very accurate and they tempt you to drive like a moron on public roads to try to get a good run. Just go to the track, its alot more fun.
