is the analizer flywheel or rearwheel horepower??

[superduty]

I wnet to my local track this weekend and in 95 degree hi humidity, and the first time out with the car all year and new fresh 306, i went 10.57 129.91mph with a 1.57 60' i couldnt hook up to save my butt. but this analizer says the same mph i ran, but my et was slower, but it was hot, i didnt try and tune it and i spun bad. If i enter all my info in it, it comes out in flywheel power according to my mph i ran. i just have to get it to hook up on a cooler day and then it will run cloe or the same as the analyzer says. Just my opinion on the flywheel power, since i ran the same mph it gave me when i entered my flywheel and weight info
