Jay I have not but I have seen some "generous" dynos that the motor never "ran the number" by the wt/mph on the car. The "stingy' Stuska we used on my 455 pump gas in my TA was below what the calculators say. 525 on the dyno 124 MPH weighing 3750. 587 on Wallace calculator. Pump gas and a Torker II not a Northwind!
