I would love to see other people compare the two, most dyno places do four runs for your money, i was lucky enough to do 6 on the day, 2 power runs and a fuel run.
As for the mods, yes most peoples mods are different but how much difference will there be between what we do, I/H/E pretty much all similar, the biggest factors will probs be the dyno!
PLUS what was the spoon ecu mapped for? What mods etc? Custom map will always be the way!
These runs were done on the same dyno on the same day within the same hour, with out the car moving out the rollers, not two months apart at different dynos, where other factors such as, air pressure, air tempreture, tyre pressures, alignment of wheels, tightness of ratching the car in place, dyno control, type of dyno, the way the dyno is calibrated etc. There are countless factors that affect the outcome!
