This... Everything I have ever read states that every dyno even within the same brand are somewhat different and to only compare the gains of the same car on the same dyno. Just google "mustang dynamometer vs dynojet" Therefore IMO these stated numbers are worthless.It’s hard to say and see how the power curve is compared to stock without a dyno run on the same car without the tune.
They may be spot on, maybe, but you are using calculated losses, you have correction factors, and then there is the question of the dyno's calibration. These are really baseless numbers. An unscrupulous vendor can make them say whatever you want. We really need before and after runs.
Hopefully someone somewhere along the way will be able to fill in the gaps. Glad to see more ECU tuning options for the car!
