But I do doubt the roads, the possibility of a decline to enhance results etc.
A drag strip is a level playing field, a constant other than weather variables.

Actually you would be surprised by how much tracks vary. After making many runs you will find how remarkably consistent the vbox is. Sometimes I can even pick out differences between the drag strip lanes. As far as slopes...mine is within .16% which is flatter than many drag strips. I was going to start doing some more 1/4 mile work....but after just hsving the EGR recall...the car feels very weak. I confirmed it with the vbox...as the car only traps 97mphto now. Its crazy. I should have refused the recall. Has anyone else experienced reduction of power post-recall?
