Yes correct it is a tuning tool and figures don't bother me however when comparing this dyno to 90% of the other dyno's in Ireland it's down anywhere from 10-20% in comparison of power readings hence the Dyno Dynamics obtained the name "heart breaker dyno" or "Ego killer"
It's often the case I get car's to map which were dyno'd elsewhere some time ago and lets say for example the car made 200bhp on the other dyno and then on the DD it's making less after mapping some take this badly and can't get there head around it as in there mind they have gained no power although most people come around after they drive it and feel the extra power with their butt dyno
@Ricky, was nice meeting you and I can confirm this car looks as good up close as in the pics
The dizzy rotor screw sure made mince meat of the cap
