I got a Gtech meter about 2 weeks ago. It didn't take long to learn that you need a straight and real flat road to get accurate readings. Its hard to find high quality roads without bumps that don't have any traffic. After much searching I found a decent road without any traffic. I got one good run in before I had InMotion Tune the car. Just did a run today after the InMotion tune. Once I get the launch down and maybe some new tires I can improve the embarrasing 60ft times. I plan on going to a track for my first time this summer for some "official" times. Do these numbers seem to add up to you guys. 113.61mph looks high for 12.747.
