Never said mine was accurate, simply stated Veva has more than me. I simply stated on the day I went 127, Veva went 129 and that my car had dyno'd at 420. If Veva's car dynos at around 450 on Dales dyno then will that be accurate? I am comfortable in saying that my car has dyno'd at 420 because I believe Spiros dyno does not inflate figures, but I have always said that dynos are just a tuning tool and MPH is a true indication of power. I'm sure there are enough posts of ET's, MPH and RWKW readings that you can get rough idea of how much power it takes to get a certain MPH. Just remember ZF cars will show higher MPH than BTR cars and Manuals will show less MPH again.
