FYI you can skew the numbers so easy on a mustang dyno. You can easily make them read 100 hp over actual and 100 hp lower...set the weight wrong watch numbers change, change the weather station...watch numbers change....set smoothing to zero watch numbers change.....set smoothing to 100 and watch numbers change
now on the DJ the numbers arent as easy to Skew
on a MD they have a DJ setting so it gives off the same reading as it would on a DJ
