hey man hows it going?? just looking through some of the forums and I seen your under the hood chevy mod. Im looking into doing that as well and your is by far the best I have seen. How exactly did you go about doing so?? Thanks
DA is Density Altitude....It is the combined calculation of : Temp.,Humidity, Barometric Presure, and Altitude where & when you make your runs.....Example : A run with a Minus 1,000ft. DA will be much faster than a run with a + 2,000 ft. DA
The higher the DA the SLOWER the runs.
